Compressor shell and exhaust pipe girth welding machine is an annular welding for welding compressor shell and exhaust pipe tailored by Anjia for customers according to customer needs, according to product materials and welding processes. machine. Because this welding machine is customized with special welding fixtures, it can ensure that the welding does not move, ensure the welding pressure is stable, ensure the welding penetration depth and stability, and no longer have welding slag and pores, and solve the leakage. Problems to ensure welding quality. The scenario when a customer finds us is:
I. Customer background and pain points
Hl Co., Ltd. is a leading manufacturer of refrigeration compressor parts in China. It is a professional manufacturer of housings, cylinders, accumulators and other products for air-conditioning compressors. At that time, customers needed annular convex welding of the compressor casing and the exhaust pipe, but The following problems they encountered when welding with previous welders:
1. Low welding yield, many spatters, and welding slag;
2. The welding depth is not good after welding, and there is leakage;
The customers of the above two issues are very distressed and have not been able to find a solution.
Second, customers have high requirements for equipment
HL found us again on May 23, 2018, discussed with our sales engineers and wanted to customize the welding machine with the following requirements:
1. Zero leakage is required after welding;
2. No spatter or welding slag after welding to ensure good yield;
3. The welding efficiency is required to be increased by 30% on the original basis;
4. The yield rate should be increased by 50% on the original basis;
5. Solve the problem of welding instability;
6. The welding cycle must be the same as the last one to reach 4S / piece.
According to the requirements of customers, ordinary standard spot welding machines cannot be realized at all, what should I do?
3. Develop custom compressor casing and tube ring convex welding machine according to customer needs
According to the customer's requirements, the company's R & D department, welding process department, and sales department jointly held a new project research and development meeting to discuss the process, fixture, structure, feeding method, and configuration, list key risk points, and make one by one The solution, the basic direction and technical details are determined as follows:
1. Workpiece proofing test : Anjia Welding Technician made a simple fixture for proofing at the fastest speed. We used our existing projection welding machine to proof test. After 8 days of back and forth testing on both sides and doing flaw detection and gas detection, we reached them. The welding requirements, determine the welding parameters;
2. Equipment selection : The R & D engineer and the welding technologist communicated together and calculated the selection power according to the customer's requirements. Finally, it was confirmed as ADB-480 custom intermediate frequency inverter convex welding machine;
3. Stability of equipment : Our company adopts all "import configuration" of core components;
4. Equipment advantages :
1) We have selected high-power intermediate frequency inverter power supply with short discharge time, fast climbing speed, fast welding efficiency, good nugget, and can save 30% of energy;
2) The machine body has good rigidity, and a special welding fixture is customized to ensure that the welding does not move. This ensures that the welding pressure is stable, the welding penetration depth and stability are guaranteed, and there is no welding slag and air holes after the welding gas detection. Leakage problems ensure welding quality;
3) Easy to operate, ordinary workers can operate, professional welders are needed in a hurry, saving labor costs.
4) The welding efficiency can be increased by 40% on the original basis;
5) The yield rate is high, which has increased by 60% on the original basis.

5. Delivery time: 30 working days.
Anjia discussed the above technical solutions, details, and HL in detail. After the two parties reached an agreement, they signed a "Technical Agreement" as the standard for equipment R & D, design, manufacturing, and acceptance, because our consideration of details was in place and won the trust of customers. On October 10, an order contract was reached with HL.
Fourth, fast design, on-time delivery, professional after-sales, and get praise from customers!
After confirming the equipment technical agreement and signing the contract, Anjia's project manager held the production project launch meeting as soon as possible, and confirmed the mechanical design, electrical design, machining, outsourced parts, assembly, joint adjustment time nodes and customers to come to the factory for pre-acceptance. , Rectification, general inspection and delivery time, and orderly issue work orders of each department through the ERP system, supervise and follow up the work process of each department.
The time passed quickly and 30 working days passed quickly. The HL custom compressor casing machine and exhaust pipe ring convex welder were completed after aging tests. Our professional after-sales engineers went through the 3 days of installation and commissioning at the customer site. And technical, operation, maintenance training, the equipment has been put into production normally and all reached the customer's acceptance standards.
HL is very satisfied with the actual production and welding results of the compressor shell machine and the exhaust pipe ring convex welding machine, helping them solve the welding yield problem, improve welding efficiency, save energy, save labor, and give us high recognition. And praise!
