Most of the currently used carbon steel welding arc welding. To improve the crack resistance of welded joints should be used in low-hydrogen electrodes. Individual circumstances, may also have calcium-based titanium and ilmenite acidic electrode, but this time the process should take strict measures, such as preheating before welding, to reduce the fusion ratio (reduced weld carbon content), etc.

Arc welding of carbon steel rod of choice when
Special circumstances, can be used in chrome-nickel steel welding Stainless Steel Electrode, such as E0-19-10-16 (A102), E0-19-10-5 (A107), E1-23-13-16 (A302), E1-23-13-15 (A307), E2-26-21-16 (A402), E2-26-21-15 (A407), etc., due to the plasticity of austenitic weld metal sound, can reduce the welded joints stress, even if no preheating before welding weldment, heat affected zone can also be generated to avoid cold cracking.
