Welding depends on the electrodes for the creation of the electric arc, if these important items of equipment are not quality, then the whole process could suffer. Welding electrodes consists of metal wires covered in chemical coatings in order to prevent metal deterioration; this very structure makes the arc more stable or creates a better weld. There are several factors that determine the type of welding electrodes used: first of all the nature of the metal meant for the welding is crucial, then there are the machine and the work conditions as well. For instance, you cannot use the same welding electrodes for steel as for aluminum or brass.
Depending on their structure welding electrodes can be classified in consumable and non-consumable, the former are twice involved in the welding process, whether the latter contribute to it without suffering any changes. Some welding techniques require that the flux coating of the electrode be burned during the procedure: it may create smoke that shields the weld being made from the air around, or it can melt and mix with the metal for a better elimination of the impurities. According to a standard measurement, welding electrodes can be identified due to a numbering system that ranges from 1/16 to 5/16” in diameter; the best way to find the correct welding electrodes is to know which match the process you need them for.
One key-element for the safe preservation of the welding electrode properties is that it be kept dry, since humidity lowers the quality of the coating, which may finally result in a poor weld. This is why it is not uncommon to use special ovens to heat welding electrodes and eliminate all traces of humidity; this is the regular procedure when the electrodes have been exposed to a wet environment for more than several hours. You may also choose to deposit them in moisture proof containers in order to avoid future damage.
The metal-arc welding electrodes can also be classified according to the type of coating; thus we’re talking about heavy and light coated electrodes and bare electrodes. The choice of the best type depends on several peculiarities, corrosion resistance is first on the list, followed by material ductility, the position of the weld and the strength necessary for the welding process. Choosing an inadequate type of welding electrodes may severely affect the quality of work.

I’m sure I lived in that building. In the aparment those two windows on the right go in to. This is really weird to see.
(my username is purely coincidental btw)
oh my god. stupid landlords.
My suggestion is that you take one of those 6 week welding courses at the local college.
You just don't start by reading a book.
Now i have an office job, but i have been a welder fitter for 20 years.
Make sure the first thing you buy is a fire extinguisher
The fabrication of hull of large ships is normally done by panels assembled into blocks then the blocks are assembled into sections of the vessel and finally the sections are joined to form the hull.
First, panels consisting of plates and stiffeners are made. In the fabrication of the panels submerged arc welding is most suitable since most of the welding are made on flat surfaces and these can be done using automatic welding machines. Several of these machines can be run by a single operator
.For the assembly of the blocks however, most of the welding operations are done manually because automatic welding machines may no longer be suitable.
Manual arc welding is also used in the assembly of the blocks to form a section of the vessel and also for welding the sections of the hull together.
get an arc welder that has at least 200 amps dc
a name brand such as lincoln miller etc
practice with the 6013
switch to 7018 for higher strength
mig welds are strong but brittle they will break without warning if overloaded
and yes i know a lot of shops use the mig on everything
but if they see what i see all of the time they wouldn,t
arc welds will usually start cracking before they fail
on the lighter metals you are talking about the mig would be ok or if you plan to do any aluminum welding
but if you want to go to heavier metal later the arc welder is better
most of my welding is done on 3/4 inch or thicker metal
i will use my mig if it is nonstructural
if you think what i say about a mig is not true try fillet welds on 1/4 inch plate then bend them
you use what is most comfortable you need to be able to see the puddle of molten metal to make sure you have good penetration and a decent looking bead I prefer a glass #10 and a glass cover plate how ever I'm thinking of buying a self darkening helmet as the price has come down to around $ 50 the auto darkening system has been on the market for about 15-20 years my brother bought one when they first came out and paid about $ 275 but the novelty wore off for him you can get a auto darkening from http://www.harbor freight.com Do not look at the light with out a welding lens as you will burn your eyes out!
you may want to do a search on that (google). That may give u the help u need. Good luck!
welding is a physically demanding job, regardless of the type, most of the time you are sitting or standing for long periods of time, but it is also a great trade to have, if your asking about strength, it depends on the job, if you are production welding then you do not need to be very strong, but if you are a welder-fitter you would need alot of strength, because you would be handling material by hand and it can get pretty heavy, basically its up to you to know what type of welding you want to get into, and if you feel that it would be right for you in a physical sense. hope that helps with your question, good luck.
good job fera!
Do not use welding glass. It does not protect camera lens at all.
Go to a store and buy appropriate filter even a bigger one and attach it to your camera.
Ramshack-ian!
Crazy. . . It’s awesome that you got it all on video though. I’d love to see the welder guys deny that in court.
You'll probably need a formal internship or apprenticeship. Especially in this economy, there's no shortage of experienced workers.
The WPS is the specific directions instructing the welder in how to execute the weld. It would specify method (mig, co2, stick, submerged arc, etc.), material for the base metal and the filler metal, directions of travel, position of the weld (horizontal, vertical, angular, etc), voltage, and similar variables.
Any WPS must be qualified to demonstrate that it produces the weld characteristics that are desired. It then becomes the recipe so to speak for each welder to follow.
A WPS is typically written by a person experienced in welding.
