The Process Flow & Duration Estimation
The production process of metal welding parts requires precise process control and high-level technology to ensure that the welding parts meet quality standards and meet the special requirements of customers. The following are the main steps in the production of metal weldments:
Step 1: Design and drawing validation
Before production, the engineer will provide the design plan and technical drawing of the welding parts according to the customer’s requirements and design requirements. Design drawings including welding size, shape, material requirements, as well as welding process selection. Ensure that the design conforms to the feasibility of production, and after customer confirmation to the next step.
Step 2: Preparation of materials
According to the design drawings and process requirements, select the appropriate metal materials (such as steel, aluminum, stainless steel, etc.) . In this step, the material is pre-inspected to ensure that its quality meets welding requirements. In addition, the selected materials also need to be cleaned to remove surface dirt, grease, oxides, etc. , to ensure the smooth progress of welding.
Step 3: Cutting and machining of workpieces
The metal material is cut to a shape and size suitable for welding according to the design dimensions. Common cutting methods include laser cutting, plasma cutting, shearing, etc. . After cutting the metal parts usually need further processing, such as grinding, deburring, etc. , to ensure the accurate size of the workpiece and good welding contact surface.
Step 4: Prepare for welding
Before welding, the welding area needs to be inspected and prepared. First of all, check the fit of the welding workpiece, to ensure that the fitting accuracy of the joint part to meet the requirements. Then, according to the selected welding process (such as arc welding, argon arc welding, MIG welding, etc.) , prepare the appropriate welding materials and shielding gas. Make sure the equipment is debugged and the welding environment is in accordance with the safety standard.
Step 5: Welding operation
Cleaning and deburring: after the casting is removed, there may be excess metal or burrs on the surface, which need to be cleaned by grinding, sandblasting, etc. .
Welding Process Control: to ensure that the welding heat input, molten pool size, welding speed, etc. in line with technological requirements.
Welding Monitoring and adjustment: real-time monitoring of welding in the welding process, if there is a problem can be adjusted at any time process parameters.
Step 6: Post treatment of welding
After the welding is completed, the welded joint needs to be post-treated to remove the residues and oxides generated during the welding process to ensure the strength and appearance of the welded parts. Common post-processing methods include:
- Weld cleaning: use brush, sandpaper and other tools to clean the weld slag around the weld.
- Deoxidation: the use of chemical or mechanical methods to remove oxides in the welding area to prevent corrosion.
- Heat treatment: some welded metal parts may need heat treatment, such as annealing, normalizing, etc. , to eliminate stress and improve strength.
Step 7: Quality inspection
After welding, the metal parts need to go through strict quality inspection to ensure that each product is in accordance with the design standards. The testing items include:
- Dimensional inspection: ensure that the dimensions and shape of the weldment are in accordance with the design drawings.
- Weld inspection: through visual inspection, ultrasonic testing, X-ray inspection and other methods to detect the existence of weld porosity, cracks, lack of penetration and other defects.
- Strength test: tensile, bending and other physical properties of welded parts are tested to ensure that its strength and bearing capacity meet the requirements.
Step 8: Packaging and shipping
After quality inspection of qualified welding parts into the final packaging link. According to the customer’s requirements and product characteristics, select the appropriate packaging, to prevent damage during transportation. Packaged products will be shipped according to the order arrangement to ensure timely delivery to customers.
Step 9: Delivery of finished product：
Upon completion of all inspection and post-processing, the castings will become the final product, ready to be delivered to the customer or used for assembly.
