What is 4g welding?
4G is a welding position. The '4' means the weld is to be made in the overhead position. The 'G' means the weld is a groove weld.
What is stick welding?
Stick welding is a process in which a metal joint is fused together by the intense heat generated by an electrical arc. The "stick" in stick welding comes from the stick electrode that acts as the arc emitter and as a filler rod. It is used in various welding applications especially for heavy metal work. It is commonly used for this because of the ease of transmitting a powerful arc though the stick electrode.
What is the material used for tac welding?
Tac welding is not a specific material. Tac welding is a form of welding, that welder's use in order to hold two pieces' of metal together to get a proper fit. The tac weld can be easily broken if the two pieces' of metal aren't in the right place. So if you tac weld anything, the filler is going to be whatever material you are welding.
Do have to take stick welding before tig welding?
I was taught oxy/acetylene welding first, then stick. TIG welding is just like oxy/acetylene except much easier (less variables and a foot control to make minor corrections or even pulse the weld) I would recommend you learn both. TIG welding for precise/clean welding. Stick for some larger, perhaps special welding (hard facing tools - bigger pieces of steel).
What does a welding instructor do?
Teach you how to weld
What welder can be used to weld a least five sixteen inch thick steel?
Tig, mig , or If you are as good as me stick welding will all work
How close can one weld be to another weld?
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
What is the welding method and welding rods for weld EN 24 steel?
d2
What is the difference between shielded and unshielded welding?
Shielded welding needs a gas to shield the weld from the atmoshere air. Unshielded uses a flux the burns when welding to shield the weld from the atmoshere air.
Can metallic bonds be formed from a welded joint?
Yes, welding of metals typically involves heating and fusion in resistance welding, arc welding, acetylene torch welding. Metallic bonds are formed between the substrate and the weld. The composition of the weld and the substrate around the weld inevitably is different from the material being welded.
How much are classes for welding?
Classes for welding are to help you learn how to weld and how not to burn yourself. They have books on how to weld and everything to do with it.
What is the function of slag for welding?
The slag in the welding process protects the weld from oxidation and slows down the rate at which the weld cools. It also prevents brittleness of the metal.
