Welding distortions are the undesirable characteristics that are hard to eliminate in steel joints. However, with the submerged melt welding technique these distortions and anomalies are less existent because the high heat and better speed of metal deposition negates the possibility of the inconsistencies. 4. The presence of the flux channel tools steels heat treatment of tool steels including Submerged arc weldingStainless Steels Welding Guide - Lincoln Electricstainless steel is generally helpful in welding. Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel. In resistance welding, lower current can be used because resistivity is higher. Stainless steels which require special welding procedures are discussed in later sections. 3.1 FERRITIC
