Factory Tour

Established in 1993, Shanghai WTL Welding Equipment Manufacturing Company is dedicated to the design and manufacturing of welding and cutting machines. We are proud to take that experience and expertise to seek creative and consistently improving ways to serve our customers. Based in Shanghai, China, our factory spans 25000 m² and supports an annual production of 240,000 machines. Such a large production capacity is backed up by 4 assembly lines as well as an SMD workshop, parts workshop, SMT manufacturing workshop and an automatic warehouse. This means that each product undergoes multiple testing rounds, including pressure tests, aging tests, no-load and load tests, welding tests and functionality tests before they are launched on the market. In doing so, we guarantee each machine’s stability and performance.

  • R&D center

    WTL has a skilled R&D team with over 30 dedicated, driven and creative engineers, which is in charge of 3 expert engineers who have more than 10 years of R&D experience. The rich experience and cooperation guarantees we offer our customers nothing but the best in products and quality.

    We carry out strict test in the whole R&D process. We will always follow our test steps to test the first machine, first five and twenty machines before a batch manufacturing, greatly enhancing machine quality and performance. The testing details are described as below:
    1. The first machine testing
    - Function test
    - Duty cycle test at 40 ℃
    - Temperature rise test for key components
    - Internal components temperature test made by infrared thermal imaging camera
    - IGBT input current/voltage test
    - Diode peak output current/ voltage test

    2. The first five machines testing
    - Function consistency test
    - Test of all input voltage ranges (±15%)
    - Long-period load test (under all input voltage ranges at 0℃/25℃/40℃)
    - Stall test

    3. Twenty machines testing before mass production
    The machines passing various tests will be delivered to different customers for getting feedback from the actual application. According to the customer feedback, product performance and quality will be then optimized before mass production.

  • SMT workshop

    Our SMT workshop is staffed by 40 employees who have a minimum of 2 years of experience working in SMT and related areas. They work alongside our 4 main production lines for inserts and welding, allowing for a daily production of 3,000 machines. We have also introduced advanced production equipment from Europe and Japan, including JUKI’s SMD soldering machine as well as ERSA’s peak-flow oven and reflow soldering machine. Currently, all components and production processes in the SMT workshop are lead free and compatible with RoHS standards implemented in the latter half of 2019.

  • SMT fabrication workshop

    Our SMT fabrication workshop is equipped with a Swiss Bystronic’s laser cutting machine, German Trumpf CNC punching machine, Italian Gasparini and Swiss Bystronic’s CNC bending machine. All of this advanced production equipment has been imported and guarantees our production speed and accuracy.

    The maximum welding material thickness available is 15mm, and we support a precision of 0.1mm. With the two German Trumpf CNC punching machines and various molds with different sizes and functions, we are capable of processing 2500*1250mm standard material of a maximum thickness of 4mm, and an operations precision of 0.1mm.

    Our Italian Gasparini and Swiss Bystronic’s CNC bending machines support welding materials at a length of 2100mm and 3100mm. We can also change different molds according to customer needs.

  • Powder coating workshop

    Our dust-free workshop is equipped with a Swiss GEMA automatic tunnel powder coating line, and we use automatic spraying machines for surface treatment. The components all go through a 2 time oil removal process, two water washing processes, a surface adjustment, phosphating and a final water washing. Later, all coated components will undergo a variety of different tests, including shop, adhesion, salt spraying and more.

  • Assembly workshop

    Our assembly workshop is equipped with 11 assembly lines, which are designed to carry out general assembly, screen printing, debugging, aging test, packaging and more. The daily production reaches 1,000 machines.

    There are 4 assembly line in this workshop, guaranteeing an annual production of 24,000 units. Each of our products undergoes extensive testing, including pressure tests, aging tests, no-load and load tests, welding tests and customized tests, all to ensure the stability and performance of our machines. Most employees have 2 or more years of experience and expertise in this area, with a first-time pass rate reaching 98%.

  • Testing
    With our own inspection team, all procedures will undergo strict testing:
    • Raw material test: we are equipped with a variety of testing machines, including a voltage resistance tester, multimeter, and bridge meter to take random inspections on raw materials and full inspections on special components such as transformers.
    • Semi-finished product inspection: we will conduct torsion, tensile and ground conductivity tests for our semi-finished products in order to guarantee the uniformity and reliability.
    • Finished products inspection: Each of our products undergoes extensive testing, including voltage resistance tests, aging tests, no-load and load tests and appearance tests, thus guaranteeing the stability and performance of our machines.
