most problems in welding are caused my the welding puddle being contaminated in some way. Lack of shielding gas (empty tank, of wind blowing it away) lets oxygen into puddle. Dirty material (rust, paint oil) allow the contaminants into the puddle, which in turn can cause the weld to distort or crack, or even burn through the base material.
Inconsistent torch angle while welding causes variation within each quench line (appearance of weld,) which may cause a weld to be undersized based on a fabrication print or could cause undercut by not filling in an edge that was melted away.
Clean and consistent welds, with the proper prep routine will usually work in the end

What is the welding defects for MIG welding?
You can find pretty much all welding defects in Mig welding. There are some that are morelikely to appear than others but that is depending on the gas and power range that is being applied. The defects are: porosity, incomplete penetration (mostly in case of short circuit transfer) undercut, excessive concavity/convexity (incorrect amperage/voltage ratio), cracks (cold and hot) incomplete fusion (wrong torch angles), cold lap.
What is the difference between Tig weld vs plasma weld?

What is a base metal in welding?
A base metal is also called the Parent metal. It is that metal in the welding practice that has been cut by the various forms of cutting, then prepared and is to be welded. Welding is performed to join one section of the base metal to another section of base metal by means of the various welding processes, e.g. SMAW(Shielded Metal Arc Welding) where welding welding rods are used, GTAW(Gas Tungsten Arc Welding) where Tig wire is used, FCAW(Flux Cored Arc Welding) etc. The welding rods, the TIG wires etc are called the filler metals, for they fill the weld gaps by depositing their molten-state weld metals.
Welding jobs if you went to a welding school and graduation?
Graduating from a welding school can open up various job opportunities in the welding industry. Welders are in demand across sectors such as manufacturing, construction, oil and gas, automotive, aerospace, and more. Some potential welding jobs that can pursued after welding school are: 1.Welding Instructor 2.Welding Technician 3.Welder/Fabricator 4.Structural Welder 5.Pipe Welder 6.Welding Inspector
What is the cost of welding machine in india?
