There are different types of welding defects that can transpire during the welding process. From porosity and cracking, to burn through and undercut, each has several causes. However, regardless of the appliion and material on which they occur, one thing remains true to all of them; they’re common, costly, cause downtime and loss of productivity.
Hardfacing, also known as hardsurfacing, is the appliion of buildup or wear-resistant weld alloys to a part''s surface by ways of welding or thermal spraying. It is welded to the base material, and generally takes the form of bare filler rods for oxy-acetylene (oxy-fuel) and TIG (GTAW) welding or covered electrodes for arc welding (MMAW, SMAW).
Welding with self shielding flux core produces faster welds – compared to solid wire. Flux core is better for galvanized steel or welding hard to weld steel. Is amenable to the skill or rather the absence of skill of the user than welding with solid wire and shielding

The filler rods don''t penetrate as deep. They build up weld. Stabilizers in the flux make 6013 welding electrodes one of the simplest rods to use. With a slightly heavier slag covering, try to keep the arc in the puddle. 6013 rods can also be run either up or down on
The general term “hardfacing” means to put a protective layer of material on a surface to prolong the life of the part. A more appropriate word to use for this activity is “wearfacing.” To effectively wearface a part and extend its life, a basic understanding of hardness, types of base metals used in wearfacing, types of wear, and types of filler alloys is needed.

Four types of contact tip types are most commonly used in welding appliions (as well as one for laser welding), and each has its pros and cons: #1: Standard Copper Welding Contact Tip (E-Cu) A standard copper welding contact tip has a relatively high current transfer rate at greater than 55 S/m* electrical conductivity, and it is used mostly in hand-held welding appliions.
Due to the heavy-duty nature of the method, MIG welding is a typical technique in hard facing, which entails welding rough materials onto base metals. You have MIG welding to thank for some of the parts you see on tractors, cranes and other types of rolling stock.
