The materials used for our tanks, vessels and silos can be stainless-steel (AISI 304, 304L, AISI 316 and 316L etc.) as well as aluminium. In accordance with the client’s requirements, Cavalzani Inox can also attend to the treatment of the internal and external surfaces of the steel tanks with sand-blasting, priming and enamelling.
In order to complete the service, Cavalzani provides customers with various types of stairways, handrails, gangways, level measurement systems and anything else needed in order to render the cisterns and vessels perfectly functional.
Our technical staff has always been investing in research and development to be sure of offering customers only the best storage solutions. It is worth mentioning the constant cooperation with the University of Florence over the past twenty years.
By joining technical and mechanical skills to new electronic technology Cavalzani Inox is today able to offer tanks and storage systems which offer, besides the quality which has always been one of our distinguishing features, excellent automatic systems and remote control allowing us to obtain the maximum possible from a minimum of effort.
To guarantee only the highest quality standards, we use an automated welding system for the production of our tanks including:
- 5 bench-stops for the viroles
- automatic TIG welding machinery with resource support (as specified by the Italian Welding Institute)

Help answer the question about tig welding
if ac current is used for aluminium tig welding,will the heat of arc temp increase more than dc current?When dc current used for aluminium,arc temp is less compared to melting point of al oxide.then when using ac how it increases?

The short answer is no.
There is not a massive amount of industry around the coastal areas of spain , and any welding work would really be centred around making Gates , Fences and Rejas ( Security Grilles ). If this is something that you are able to do then my advise would be to looking at starting this as your own business because you would struggle to find reasonably well paid work like this on a permanent legal contract here in Spain
Mig and TIG welding are all arc welding. TIG is arc welding in the presence of a tungsten electrode which is non-consumable and an inert gas and the welded material. This is usually used in the aircraft industry. MIG welding is still arc welding in the presence of argon and wire feed consumable. TIG is usually a better welding technique. These are different from stick arc welding which uses flux coated sticks in developing an arc.
There is a big difference between MIG and TIG welding, in both the process, and the skill level required of the weldor. They really are two different processes altogether, and the MIG is the much easier of the two.
There is much to read on the web, including some great information at the Miller and Lincoln websites. They can give you a pretty great overview of TIG welding. But, as with many skills, it takes hands-on practice as well as study, to be successful.
If your fiance has ever welded with a gas torch, he might already have the skills he needs. Unlike a MIG welder, a TIG does not feed an electrified filler wire for you. You are in control of a separate heat source (the torch) that you must manipulate in order to melt the base metal together, while adding the filler by hand to the molten puddle you're creating. It's the same way a gas torch works, just with electricity, rather than gas, as the heat source.
The tricky part comes in learning how hot to make the puddle, how much heat to apply (with a foot or hand controller), and how to coordinate the filler at the same time. Quite often, TIG welding involves metals like aluminum or stainless, which have their own quirks that need to be considered. It's by no means impossible to learn all of this…and it can be a very valuable skill to have, often paying higher than MIG welding jobs.
If your fiance shows this prospective employer that he is a professional who takes pride in his work, has studied the subject, and is willing to learn, he may get his foot in the door and start down a new path on his welding career. I wish him the best. Study all you can, and if you know a buddy who is good with the Oxy-Acetylene torch, go visit him right away for some practice!
Best of Luck!
What you have to your advantage is being able to Oxygen- Acetylene weld. You need to be able to use both hands. One to manipulate the TIG Torch and the other hand to feed and dip the filler wire. Good Luck !
What's your question?
I was working for a company welding aircraft parts. APU assemblies for boeing, lear, and raytheon. I was recieving $18 and hour but would have been able to make more through raises and fringe benefits. i ended up quitting because they cut out all overtime. I need certs for all kinds of AL, S.S., And CrMo. I had to get tube, and plate from .020 to .375 certs before I even started welding on the parts and that took a couple of weeks….
I think a lot of people hear about guys making $40 an hour and think they can jump in on that but what they don't realize is those guys have been doing it for years and have recived annual raises etc.
You will weld in accordance to the weld procedures that will be given to you for the specific materials mentioned.

What is right for you, MIG or TIG? For certain type of work TIG is required, like welding chrome moly for some racing organizations. Intricate work, like gunsmithing is also well suited to TIG. TIG is used by many auto restorers who prefer a more precise, perfect finish that requires little to no finish work. TIG is most similar to gas welding in technique, so if you've done oxy-fuel welding, TIG should be a natural transition.
TIG stands for Tungsten Inert Gas welding. Also called GTAW (Gas Tungsten Arc Welding) and Heliarc® which was Linde's trade name for the TIG process when it was introduced many years ago. The arc is started with a tungsten electrode shielded by inert gas and filler rod is fed into the weld puddle separately. A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding.
MIG is required by law and by insurance companies in many localities for structural repair of automotive frames. MIG is also much easier to learn and faster to weld. For doing other types of welding, like sheet metal, it can be a matter of personal preference. For an auto body repair shop or a novice welder, a MIG is a good, practical all-around welder.
After welding and if application is critical , solution annealing is preferable.
When you talk about pulse tig it is mostly DC welding. You use the pulse to help reduce the distortion. It is mostly used on all ferrous metals. You do not need or have the pulse feature on AC for aluminum. You would need an AC or AC/DC machine for tig welding aluminum. They are some what costly. When tig welding you need to stay with the better name brand welders. Thermal arc, Hobart, Miller, and Lincoln are all good machines. To weld 1/4" aluminum you need approximately 200 or more amps. So this puts you into a machine that is in the $2000 range. Then you need a bottle of argon gas. If welding for any length of time at those amps you would need a water cooled torch. Not to mention the water cooler, foot pedal and all the other items needed. All these items are costly. I am not trying to discourage you but you need to know it is going to cost you some bucks to invest in all the equipment you will need. Good luck!

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.
GTAW is most commonly used to weld thin sections of stainless steel and light metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing procedures such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.
