Process evaluation device and process evaluation method for butt welding of cast steel and low alloy steel

Abstract

The invention discloses a cast steel and low alloy steel butt welding process evaluation device and process evaluation method.The cast steel and low alloy steel butt welding process evaluation device comprises a structural part protection part, a heat preservation cotton plate and a horizontal placement part, protection cotton is arranged in the structural part protection part, and the horizontal placement part is arranged on the structural part protection part; the two welding materials are horizontally placed on the upper portion of the structural part protection part through the horizontal placing part, a welding groove is formed between the two welding materials, the heat preservation cotton plate is correspondingly arranged under the welding groove, and the structural part protection part is provided with a shielding gas assembly corresponding to the welding groove. The structure protection part of the box body structure is arranged, the cast steel plate and the low alloy steel plate are horizontally arranged on the structure protection part through the horizontal placement part, heat preservation or shielding gas protection on the welding position is achieved through the heat preservation cotton plate and the shielding gas assembly based on the to-be-evaluated welding process, and therefore process evaluation is facilitated; by means of the process evaluation method, the operation cost of follow-up actual welding can be greatly reduced, and guarantee is provided for engineering construction.
