摘要

连续热镀铝锌生产线的窄搭接电阻缝焊过程中常出现焊轮打火问题，导致焊缝质量下降造成断带，从而引发产线停机，因此需要对电阻焊过程中焊轮打火的原因进行分析。主要针对焊接电流、焊轮与钢带之间的接触电阻、钢带与钢带之间的接触电阻等因素进行探讨。分析发现，焊轮与钢带之间的接触电阻增大是导致焊轮打火的主要原因：焊轮表面的污染物会显著增加接触电阻，导致热量过大，烧穿焊缝；钢带表面的清洁度也对接触电阻有显著影响，导致电流分布不均，产生打火。此外，根据钢带厚度选择合适的焊接电流对于控制焊接过程中的打火现象也至关重要。

Abstract

During the narrow lap resistance seam welding process in the continuous hot-dip aluminum-zinc production line

a common problem of welding wheel ignition occurs

leading to a decline in weld quality and causing breakage

which in turn leads to production line shutdowns. Therefore

it is necessary to analyze the causes of welding wheel ignition during the resistance welding process. The main factors discussed are welding current

contact resistance between the welding wheel and the steel strip

and contact resistance between the steel strips themselves. The analysis found that the increase in contact resistance between the welding wheel and the steel strip is the main reason for the welding wheel ignition: pollutants on the surface of the welding wheel significantly increase the contact resistance

leading to excessive heat and burning through the weld; the cleanliness of the steel strip surface also significantly affects the contact resistance

leading to uneven current distribution and causing ignition. In addition

selecting the appropriate welding current according to the thickness of the steel strip is also crucial for controlling the ignition phenomenon during the welding process.
