Publish Time: 2025-10-15
Company Needs:
Quanzhou Baolong Machinery Co., Ltd. exports industrial vehicle pedal components to Europe and the United States. The company required ISO 3834 and CWB (Canadian Welding System Standard) certifications, the products were also required to pass ISO 3691 testing and certification (industrial vehicle safety standard).
Product Key Features:
● Material: High-strength steel, high-frequency heat treatment
● Operating Conditions: Requires low-temperature resistance of -30°C and wear resistance
Certification Highlights:
1. Testing:
● Low-temperature impact test (welds meet impact resistance standards at -30°C)
● Endurance test: 5 million cycles with no cracks and low wear, wear ≤ 0.3 (simulating load operation of industrial vehicles)
2. Improvements:
● Added a steel plate preheating step (200-250°C) before welding
● Welds were graded to ISO 5817 Class B.
Achievements:
● Obtained ISO 3834 and CWB welding system certifications.
● Passed ISO 3691 testing and certification.
● Widely used in industrial vehicles in the European and American markets.
