Product Description
H Beam Automatic Submerged Arc Welding Machine adopts AC frequency conversion speed regulation, stable and reliable operation, fast return, and automatic arc finding and centering device to ensure that the welding torch automatically and accurately center the target work piece. At the same time, it is equipped with an automatic flux feeding and recycling system, which is easy to operate and high in efficiency. The H-beam welding machine can increase the height of the web according to user needs.
The manufacturing process of steel structure H-shaped steel:
1. Stakeout
When scribing and lofting, clearly indicate the assembly mark, the mark of the screw hole, the position and direction of the reinforcing plate, as well as the inclination mark, the centerline reference line and the inspection line, and make a template if necessary.
2. CNC Plasma &Flame Cutting
When cutting steel plates, use a CNC multi-head (plasma) cutting machine to remove impurities such as rust on the cutting surface before cutting, keep the cutting part flat, remove welding slag and spatter after cutting, and master the use and operating procedures of the plasma cutting machine when cutting. Adjust the equipment parameters to the best value
3. Autamatic Assembly
Before the steel plate is assembled, the deformed parts must be corrected first.
There are two types of H-beam straightening machines, mechanical straightening machines (mainly straightening wing thickness less than 40mm) and hydraulic straightening machines (mainly straightening wing thickness greater than 40mm and less than 80mm). The assembly is divided into automatic spot welding assembly machine and manual spot welding assembly machine
4. Submerged arc Welding
The welding of H-beams mainly adopts gantry-type automatic submerged arc welding machine, equipped with 2 submerged arc welding machines, flux recovery devices and other devices. The connecting plates of the columns and beams are manually welded
5. Punch
Drilling equipment should use radial drill
6. End face milling& cutting
After the H-beam is welded and rectified, an end milling machine should be used for flat cutting.
7. Derusting
H-beam steel should be derusted by shot blasting machine. Shot blasting can improve the fatigue strength and corrosion resistance of steel.
8. Spray paint
After rust removal, check whether it is qualified. After qualified, perform the first step of spraying the primer, and then perform the drawing of the intermediate paint and topcoat. After completion, perform the quality inspection again to ensure that the coating at each step meets the requirements.At this point, the steel structure H-shaped steel is completed, and the packaging box can be transported to the construction site for assembly.
Advantage
H Beam Automatic Submerged Arc Welding Machine, the submerged arc automatic welding machine adopts the crawler cantilever double-car structure; two welding machines drive the submerged arc welding gun to walk on the track; the walking trolley is driven by the rack; the device can stabilize welding, and complete two at a time Welds of welds. Two welding tractors walk on the same track beam, which saves the production site, expands the working space, facilitates the longitudinal beam in and out of transportation, and is convenient to operate; therefore, the variable cross-section beam double torch submerged arc automatic welding machine is the most advanced longitudinal beam at home and abroad. Type welder. The plane adopts flexible automatic copy tracking technology for variable cross-section beams, which can automatically track welding in real time; when welding at variable cross-section positions, the position of the welding torch cannot be adjusted.
Feature
H Beam Automatic Submerged Arc Welding Machine adopts PLC programmable control technology and microelectronics technology. It has the characteristics of beautiful welding wire shape, reliable quality, high production efficiency, simple and convenient operation. The device can be moved at will without making a ground track foundation.
