BAIJIAN - Third party testing organization
The total number of physical quantities selected to ensure welding quality during welding、 such as welding current、 arc voltage、 welding speed、 line energy、 etc.、 is called the welding process parameters. The influence of process parameters on the shape of the weld seam is as follows: (1) When other conditions remain unchanged、 increasing the welding current increases the thickness and reinforcement of the weld seam、 while the width of the weld seam remains almost unchanged (or slightly increases). (2) When other conditions remain unchanged、 the arc voltage increases and the weld width significantly increases、 while the weld thickness and reinforcement slightly decrease. (3) When other conditions remain unchanged、 the welding speed increases and the weld width、 weld thickness、 and reinforcement all decrease
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific、 fair、 and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsinspection and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
