A Welding Process of Stainless Steel Control Box

Abstract

The invention discloses a welding process of a stainless steel control box. The welding process is characterized in that the wall thickness of the control box is 7 millimeters; a V-shaped or U-shaped or X-shaped groove is formed at a welding position; for a welding piece, a filling welding wire is subjected to oil removal and descaling; for welding parameters, welding current is 240 to 260A, arc length is 0.5 to 3 millimeters, arc voltage is 8 to 10V, welding speed is 5 to 10 millimeters / second, and protection airflow is carbon dioxide gas; direct current is adopted for welding, and an electrode serves as an arc carrier and also serves as a welding line filling material; the electrode comprises an alloy or non-alloy metal core wire and a welding rod cover, and the cover is used for protecting a welding line from being damaged due to air and stabilizing arc, gives rise to forming a slag layer, and protects the welding line to be formed; and an electric welding rod is a titanium welding rod or an alkaline welding rod. The welding process is simple to operate and has a good welding effect on a stainless steel plate, the welding line is flat and smooth with good airtightness, and a component in the control box is protected from outside pollution, and is ensured to be reliable in performance.

Description

Technical field [0001] The invention relates to the technical field of thick plate shell welding, in particular to a welding process of a stainless steel control box. Background technique [0002] At present, the welding of thick plate shells, usually plates of 5 mm or more, often has the problem of poor sealing performance of the weld seam. At the same time, due to the different parameter control during operation, the width of the weld seam varies greatly and the aesthetics is poor. Summary of the invention [0003] The purpose of the present invention is to improve welding quality, and provides a welding process for a stainless steel control box. [0004] The present invention provides a welding process for a stainless steel control box, which is characterized in that: the welding process of the stainless steel control box is manual welding, the wall thickness of the control box is 7mm, and the welding place has a V, U or X-shaped groove. Weldments, filler wire for degreasing and...
