Q&A About Common Problems Of Fiber Laser Welding Machine

In order to enhance everyone's understanding of fiber laser welding machines, Razortek has compiled several common problems in metal processing and provided solutions for customers to adjust when these production issues actually arise.

Q1: Can the machine weld copper, aluminum, and brass? What is the welding thickness?
Answer: Copper, aluminum, and brass can all be welded.
Generally, the welding thickness corresponds to different powers: Welding thickness of 3mm with a power of 1kw; Welding thickness of 4mm with a power of 1.5kw; Welding thickness of 5mm with 2kw power; Welding thickness of 6mm at 3kw power;


Q2: What gases are required for welding? What is the purity of the gas?
Answer: Industrial nitrogen or argon gas is generally used as a protective gas, with a purity of 99.99%. The pressure during welding and cleaning is approximately 0.15 MPa, and during cutting it is 0.7 MPa.


Q3:What are the consumables of the machine? How long is the replacement cycle?
Answer: Protective mirror, focusing mirror.

Protective mirror: The protective mirror needs to be cleaned in a timely manner. When the machine welding or cleaning effect is found to be poor, the protective mirror should be removed and wiped with an alcohol swab. 
Replacement cycle: It needs to be replaced after a few days of continuous use.

Focus lens replacement cycle: several months.


Q4:What is a three in one welding machine?
Answer: The three in one welding machine has three functions: cleaning, welding, and cutting. If you choose a machine with only pure welding function and need to replace the nozzle, you can perform welding cutting conversion. To switch between welding and cleaning functions, it is necessary to replace the focusing lens and remove the nozzle.


Q5: How to use the machine after receiving it? How to repair a broken machine? How long does the warranty last?

Answer: We have a professional after-sales team. After receiving the machine, please contact us and we will arrange after-sales personnel to guide you in using it. In addition, we have machine and software manuals as well as machine operation videos.
Our machines have almost no hardware quality issues, most of which are software usage problems. Therefore, we can guide you to solve problems through online videos or recorded videos. If necessary, we can send you PDF manuals and 1-2 YouTube video links.

The warranty period for the machine is 2 years. If there are any quality issues (not caused by human factors), we support free replacement/repair of parts and free air freight delivery.
