Zhangjiagang YaoYu all wear resistant steel plate and pipe production lines have adequate quality control, with careful welding inspection.
1.responsible for our own work and our valued customers
2.ensure the quality of welding structure or welding pieces, especially security operation
3.improve welding technology and chromium carbide overlay plate quality
4.find problems and fix it timely, avoid to rework or wear resistant steel products scrap,resulted in time, material and human waste, increase the manufacturing cost
