1,How is the welding joint quality of the spot welding machine ensured?
Answer: The welding joint quality of the spot welding machine is affected by multiple factors, including welding parameters, welding materials, electrode conditions, etc. The spot welding machine we provide is equipped with a precise parameter control system and high-quality welding electrodes, which can ensure the stability and quality of the welding joint. Additionally, we provide welding quality inspection and evaluation services, which can conduct strict testing and evaluation of welding joints to ensure that the welding quality meets relevant standards and requirements.
2,How do we install the machine?
Answer: For some simple machines, we will provide you with English operation manuals, operation videos, and online guidance and training for your engineers to easily set up the machine. For more complex machines, we will send engineers to your country to assist with installation and training. However, there will be additional costs for engineers, including wages, visa fees, round-trip airfare, and accommodation, which will be borne by the buyer.
3,How is quality inspection carried out after welding on the spot welding machine?
Answer: Quality inspection after welding on the spot welding machine mainly includes visual inspection, destructive testing, and non-destructive testing. Visual inspection mainly observes the appearance quality of the weld, such as whether the weld is smooth and free of cracks, etc. Destructive testing involves mechanical property tests such as tensile and bending tests conducted on samples to evaluate the strength of the weld. Non-destructive testing includes methods such as X-ray inspection and ultrasonic testing to detect defects inside the weld. Select appropriate testing methods for quality inspection based on specific requirements and industry standards.
