Is arc welding stronger than mig welding?
Using the correct procedures and filler material they can both have the same strength. P.S. both are considered "arc welding"
What is deposition rate in arc welding?
It is the rate at which the welding rod is melted and deposited on the work being welded
How is the root opening size determined in welding?
the root opening is the distance between joint members at the root of the weld before welding. the root opening must be accurate so that excess welding is not necessary.
Unfortunately two dimensional maps usually shows what in area shape or scale?
distortion
Unfortunately two dimensional maps usually show in area shape scale?
distortion
What are the problems that can occur with the welding activities and how these can be overcome?
Many problems can be experienced in welding including cracks, infusions and distortion. Generally these can be avoided by eliminating hydrogen, keeping temperature under control and controlling the atmospheric pressure of the environment.
What causes warpage or distortion during welding?
Warping in welding is caused by shrinkage of weld metal, faulty clamping of parts, faulty preparation and overheating of joints. Distortion in welding is caused by uneven heating, improper sequence and the shrinkage of the deposited metal.

What is working principle of inverter welding machine?
Digital Control of welding when welding
What are welding defects?
1. crack 2. spatter 3.distortion 4. haz 5 blow holes
The possibility of distortion in the case of submerged arc welding comment by giving reasons?
The heat input in the case of Submerged Arc Welding (SAW) is higher than that in manual welding process. Reason is that the welding proceeds continuously while the work is rotated. In manual welding, it is controlled by the welder besides the time gap for changeover of electrode, relaxation by operator etc.
What has the author V A Vinokurov written?
V. A. Vinokurov has written: 'Welding stresses and distortion' -- subject(s): Residual stresses, Welded joints
What is it welding sequence and explain about it?
Weld sequence would specify the order in which welds are to be made on a structure to help against distortion and residual stresses.
What is distortion in welding?
it moves Because almost all Elements expand when heated and contract when cooled. As you are welding the metal at that location is trying to expand because of the heat. Ahead of the weld area the metal isn't moving. Behind the weld area the metal is trying to contract as it cools. If the whole weld could be heated at once it would expand then contract at the same rate without distortion.
What is laser beam welding used for?
Laser beam welding is generally used for joining together components that require thin seams and minimal distortion. The process is finely directed and offers an excellent quality finish and this is why it is a popular method for making jewellery, cars and computer components.

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).
