Shielding gases which are mixtures of inert gases (Ar), oxygen, and carbon dioxide (CO 2 ) are used to suppress the influence of air and especially nitrogen. Depending on the electric welding parameters (voltage and current) and the composition of the shielding gas two different types of ...
GMAW can be used to weld different types of metals and alloys. GMAW can be performed in all positions making it most widely used welding process in industrial applications. However, it offers certain disadvantages such as higher heat input, porosity due to entrapped shielding gases and spatter. ...
1.2.2No-weld ‘No-weld’ happens when thelaser beam energyapplied to the material is not high enough to create fusion for a short segment or the entire length of the weld seam. No-weld is normally considered as aweld defectdue to the significant reduction of the weldstrength. When a sho...
Of the four types of cracking discussed here, hot orsolidificationcracks appear near the end of the solidification process in the fusion zone. They result because of the incapacity of the molten and semisolid material toabsorb without tearingthe thermal shrinkage strains due to weld solidification a...

TIG welding has become popular among DIYers, at-home mechanics, and construction professionals because it can be used with all types of metals. You can join steel, aluminum, copper, and stainless steel in a wide range of thicknesses with the TIG welding process. Of the various arc welding ...

Friction stir welding (FSW) is a solid state joining method, which has promising application potential in Mg alloys1,2,3,4,5. Extensive studies have been conducted on various series of Mg alloys subjected to FSW. Most of previous studies aimed to understand the effects of different welding pa...
The HAZ is very well represented in the welding of metals. A HAZ can also be visible in polymer welding [178,179]. A study on laser welding of PA reveals that HAZ is visible on both sides of the bond, evidenced by the bubbles [176]. The HAZ is distinctly evident in the LTW of ...
