Welding platform

Welding platform, also known as welding flat plate, cast iron welding flat plate, cast iron welding platform, flat welding flat plate, T-shaped groove welding flat plate, welding foundation flat plate, welding foundation platform, etc. The welding platform has a wide range of applications and is a basic tool for mechanical manufacturers.

The welding platform is used as the basic flat plate for riveting and welding process. There are holes and T-shaped grooves on the working surface. The holes are mainly used to clean some iron slag and welding waste during riveting and welding, and the T-shaped grooves are mainly used to fix the welded parts. Of course, welding flat plates can also be flat, that is, without holes or grooves.

Precautions for using welding platform:

When using the welding platform, the surface should be cleaned, the workpiece should be firmly fixed, and the workpiece should be removed in a timely manner after welding to prevent deformation of the flat plate. It cannot be stored in a damp and dark place. Regularly check the accuracy of the tablet.

In order to prevent deformation of the welding platform, the support should be placed at the main pivot point when installing the flat plate. When supporting, try to adjust the working surface of the flat plate to the horizontal plane as much as possible. After the inspection or marking is completed, the workpiece should be lifted down and not placed on the flat plate for a long time. After use, the working surface of the flat plate should be wiped clean in a timely manner, and then a layer of rust proof oil should be applied. If not used for a long time, apply a layer of butter and then spread a layer of white paper. A cover made of wooden boards, when not in use, cover the flat plate with a cover and strictly prohibit water droplets from falling on the welding plate/welding platform.

Welding platforms generally have a long service life as long as they are used and stored correctly. The accuracy of the working surface can be maintained for more than 2 years. When the accuracy decreases, it can be restored through debugging or scraping processes. The service life of the flat plate itself can reach 50-100 years. Therefore, during use, attention should be paid to not using and storing it in humid, corrosive, high and low temperature environments, so as to extend the service life and work quality.

Precautions for welding platform processing:

1. Clamping of welding platform: Thin cast iron plates are usually clamped directly on the workbench using support plates. The clamping force it generates is beneficial for clamping thin cast iron plates.

2. In order to ensure the stability of the clamping of the thin cast iron flat plate, it is necessary to pre process the two sides of the cast iron welded flat plate. Otherwise, the side of the support plate and the cast iron welded flat plate cannot make good contact, which will cause uneven stress and deformation of the cast iron welded flat plate.

3. When clamping, it is necessary to ensure that the reference surface of the cast iron welding plate is tightly attached to the workbench or flat pad iron. Do not use your hands to forcefully strike the cast iron welding plate, as thin cast iron welding plates have poor rigidity, are prone to deformation and fracture, and also have elasticity. Therefore, the more you strike, the less tight and clamped the cast iron plate becomes with the positioning surface. If the gap under the cast iron welding plate is caused by the unevenness of the bottom surface of the cast iron welding plate, it should be padded with iron sheet.

4. In addition, when clamping the cast iron welding plate, the clamping force should not be too large, otherwise it will cause the middle of the cast iron welding plate to protrude. After processing, the cast iron welding plate will be loosened, and the middle of the welding plate will become concave due to elastic deformation.

5. Cutting amount: When welding thin cast iron plates, the cutting force and clamping force should be small. Therefore, a smaller cutting depth (about 0.3-0.5mm or less) and feed rate (about 0.1-0.25mm/reciprocating stroke) should be used, as well as a normal cutting speed, and appropriate cooling and lubricating fluid should be used for cutting.

Welding platform material: The hardness of the cast iron HT200-300 working surface is HB170-240. After two manual treatments (manual annealing at 600-700 degrees or natural aging for 2-3 years), the accuracy of the product is stabilized.
