Embodiment 2

[0037] As another embodiment of the present invention, the element C content is 0.8%.

[0038] Manganese is the most effective alloying element to improve hardenability. Chromium can significantly improve the hardenability of steel. Chromium can significantly improve the hardenability of steel, improve corrosion resistance and oxidation resistance, and the combined effect of chromium and manganese is better. In this example, Mn: 1.9%, Cr: 1.5%.

[0039] Another aspect of the present invention provides a welding process for welding a hollow stabilizer bar using the above-mentioned welding material, which includes: firstly beveling the leaf spring 10 to be welded, preheating the leaf spring 10 and the bushing 9, Fix the leaf spring 10 and the shaft sleeve 9 with a clamp, perform laser-MIG composite welding, and perform slow cooling after welding; then clamp and fix the torsion bar 11 and the leaf spring 10, and preheat the welding seam, preheat Laser-MIG composite welding is ca...

Abstract

The invention discloses a welding material and a welding process for a hollow transverse stabilizing rod. The welding material comprises the following chemical components in percentage by mass: 0.04 to 0.8% of C, 2.2 to 2.7% of Ni, 1.55 to 1.9% of Mn, 0.5 to 0.6% of Mo, 1.3 to 1.5% of Cr, not greater than 0.015% of S, not greater than 0.15% of P, and the balance Fe and trace element. The welding process of the stabilizing rod comprises the following steps: forming a groove in a leaf spring to be welded; preheating the leaf spring and a shaft sleeve; fixing the leaf spring and the shaft sleeve through fixtures; performing laser-MIG combined welding; slowly cooling after the welding; then clamping and fixing a torsional rod 11 and the leaf spring; preheating a weld seam; performing laser-MIG combined welding after the preheating; and then slowly cooling after the welding. The stabilizing rod welded by the material and the welding process has the advantages that the formed weld seam is attractive in appearance, and the fatigue cycling number reaches two hundred and seventy thousand times.

Description

technical field [0001] The invention belongs to the field of welding, in particular to a welding material and a welding process for a hollow transverse stabilizer bar. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's consumption level, automobiles, as an increasingly popular means of transportation, play an important role in people's daily life and industrial and agricultural production, bringing great convenience to human life . The stabilizer bar technology refers to the installation of a stabilizer bar on the vehicle to increase the roll stiffness of the suspension system, which can make the vehicle more comfortable and stable when driving, and greatly reduce the chance of rollover. The most significant advantage of the hollow stabilizer bar over the solid stabilizer bar is that it can effectively reduce its weight, so as to achieve the goal of lightweight vehicles and reduce energy consumption.
