Abstract

The invention discloses a double-phase stainless steel electric welding bar, and relates to the stainless steel electric welding field of electric arc welding. The invention provides a novel titanium-calcium type double-phase stainless steel electric welding bar, which has good welding performance such as little splash, low cost, good slag removal performance and the like. The electric welding bar is characterized in that: according to the coating formula, the electric welding bar comprises the following components in part by weight: 35 to 38 parts of rutile, 8 to 10 parts of natural mica, 1 to 2 parts of potassium titanate, 5 to 7 parts of marble, 10 to 12 parts of iron powder, 1 to 2 parts of bentonite, 2 to 3 parts of electrolytic manganese, 3 to 5 parts of fluorite, 1 to 2 parts of potassium feldspar, 1 to 2 parts of sodium alginate, 2 to 3 parts of chromium nitride, 20 to 24 parts of chromium metal, 8 to 10 parts of ferromolybdenum, 2 to 4 parts of magnesite, 2 to 4 parts of nickel powder and 1 part of Teflon. The welding process performance of the stainless steel welding bar is improved, and particularly the application range of the stainless steel welding bar is enlarged during welding, so the double-phase stainless steel electric welding bar has good welding performance such as good electric arc stability, little splash, low cost, good slag removal performance and the like.

Description

Technical field [0001] The invention relates to a stainless steel welding rod for arc welding. The invention provides a novel titanium-calcium type stainless steel duplex stainless steel welding electrode, which has excellent welding properties such as good arc stability, small spatter, low cost and good slag removal performance. Background technique [0002] With the rapid development of metal manufacturing and stainless steel industry, the product technical requirements for welding electrodes used in welding process are also very high. In the current stainless steel technology, the current domestic duplex stainless steel electrode formula basically uses rutile, calcined mica, micro-carbon ferrochrome, calcium alginate, fluorite, marble, CMC, wollastonite, potassium alginate, ferromolybdenum and other raw materials. Due to the defects in the formula and material selection of the existing titanium-calcium stainless steel welding rod, there are the following deficiencies in ...
