What is the difference between Tig weld vs plasma weld?
When we are using the tig welder we getting welding defects on our blanks, but when using the plasma weld no defects are found
What it the welder called that can weld aluminum?
can weld aluminium with a mig or tig welder
Where does silica come from when tig welding carbon steel?
Silicon is added to the tig rods in production. Use a gas weld rod which does not have the silicon and the weld will be full of porosity.
How do you weld sanitary stainless steel?
The three ways you would weld stainless steel are; 1. laser 2. friction 3. TIG Only TIG should be considered for nonproduction welding.
What are Miller TIG systems used for?
Miller TIG system are well used systems. The Miller TIG systems are used for welding, calculating the costs of welding and materials, and showing how to weld.
Why do they use argon gas to tig weld?
Argon gas is an inert gas and it shields the weld from any contamination from the out side air. It shields the weld and makes it cleaner and stronger.
TIG weld Testing Techniques How do you test TIG welding on a CuNi Pipe section?
One method is Ultra Sonic Sound, another Die Penetration.
What are common solder and weld techniques used more than TIG?
mig, oxy-acetelene, arc,
Difference between tig and mig?
It depends on what you're welding and what kind of weld you need. For an extremely strong weld where you don't want to transfer as much heat to the surrounding areas, tig is the way to go. Tig has the option of melting only the source material (together), so if it is better than no material is added, then tig is the better process. If you want a small, uniform weld, then tig is also superior. Mig is wire-feed and so adds material to the pieces being welded. So it is better for filling areas or adding superior strength. If the material surrounding the weld can take the heat or doesn't matter if it is deformed or discolored, then mig welding is the way to go. A good discussion of Tig and Mig welding is here http://www.ridgecrest.ca.us/~biesiade/weld.htm.
Do you tig weld on dc straight or reverse polarity?
Tig is always done in straight polarity, i.e. electrode negative. reason: almost 2/3rd of the heat is generated in positive terminal of weld, in this case the base metal and the rest in the negative terminal, in this case the tungsten electrode. Also you don't want to deposit the tungsten electrode in the weld, do you?
What is a fusion weld?
A fusion weld has no filler material. The pieces to be joined are touching and heat is applied at the joint. The edges melt and "fuse/weld" together. TIG or Oxy-fuel Welding is used. This type of welding is considered to be pure as nothing is added to the weld.
Crater pipe in tig welding imperfection?
crater pipe is shrinkage cavity and is occurring during weld metal solidification
