[0037]

[0038] 1. Welding process performance experiment:

[0039] In the welding parameter range of current 200-350A and voltage 30-35V, the welding process performance of the welding wire was tested. The diameter of the experimental welding wire was φ1.6mm. Less spatter, can meet the welding process requirements.

[0040] 2. Weld mechanical performance experiment:

[0041] The shielding gas used in the experiment was 100% CO 2 (A) and 80% Ar 2 +20%CO 2 (B), the welding parameters are current 330-380A and voltage 32-35V. The mechanical properties of weld deposited metal were tested, and the results are shown in Table 2.

Abstract

The invention discloses a solid welding wire for gas-shielded electric-arc welding of high-strength steel, and belongs to the technical field of welding materials. The solid welding wire consists of the following chemical components in percentage by mass: 0.06-0.15% of C, 0.60-1.00% of Si, 1.50-2.00% of Mn, less than or equal to 0.025% of P, less than or equal to 0.020% of S, 0.10-0.60% of Ni, 0.40-0.80% of Cr, less than or equal to 0.25% of Cu, 0.02-0.10% of V, 0.08-0.25% of Ti, 0.002-0.008% of B, less than or equal to 0.0070% of O, less than or equal to 0.0070% of N, and the balance iron and inevitable impurities. The solid welding wire has mechanical property superior to that of a base material, is excellent in welding operation property, is suitable for a relatively wide operation process window, is mature and efficient in industrial production route, and is low in processing manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of welding materials, in particular to a solid welding wire for gas-shielded arc welding of high-strength steel (hereinafter referred to as solid gas-shielded welding wire). In particular, it provides a solid gas-shielded welding wire with deposited metal tensile strength Rm≥650MPa and its raw material wire rod, which can be used for welding corresponding high-strength steel plates in fields such as engineering machinery, construction, and bridges. Background technique [0002] In recent years, the variety structure of welding materials has changed greatly. Although the consumption of manual welding electrodes is also increasing, the proportion of the total consumption of welding materials has dropped from nearly 80% 10 years ago to less than 50%. The proportion of various types of welding wire required increases to more than 50%, especially solid gas-shielded welding wire, which has the advantages of flexibl...
