Steel Structure H Beam Assembling Welding Production Line

H Beam Shotblasting Machine
Zhouxiang Steel Structure Processing H-Shaped Steel Welding Machine H Beam Production Line
Shot-blasting machine is a kind of shot-blasting equipment, which is applied to clean the surface of steel structure welding
work-piece, H-style steel, plate and other profiles. It can clean away rusty spot, rusty scale, welding slag on the work-piece
surface, as well as welding stress, in order to remove stress and improve surface lacquer quality
and rot proofness of steel structure and steel.
1. The arrangement of chamber and shot blaster is confirmed after shot blasting simulation by Solidworks 3D dynamic software, there’s a certain angle between shot blaster and work-piece.
2. It adopts high efficiency QZ320shot blaster, which can significantly improve the cleaning efficiency, to achieve a
satisfactory cleaning quality.
3. The separation device uses the most advanced full curtain type shot and slag separator, the separation efficiency can reach 99%.
4. This shot blasting machine is equipped with automatic fault detection and alarming, has the function of time-delay and
automatic stop running after alarming.
5. It adopts filter cartridge type dust collector, dust emission within 80-120mg/m³, which can improve the working environment
6.The thickness of shot blasting area≥12mm, equipped with high interchanged Mn13 protective plate, has more than 3 years of service life.

7. Shot blaster adopts QZ3204 curve vane with precision manufacturing. The wearing parts has long service life, easy to replace.

Why we often use Submerged arc welding way in the H beam productions line?

The welding seam of H-beam is very long. So continuous automatic welding is possible.

1. High welding productivity: Submerged arc welding can use a large welding current, the arc heating is concentrated, and the molten pool depth is increased. The welding speed of submerged arc welding is fast, and the welding speed of single wire submerged arc welding can reach 30~50m/h.

2. Good welding seam: the surface of the molten pool is protected by slag and flux, which avoids metal oxidation reaction in the molten pool and improves the strength and toughness of the welding seam. At the same time, due to the fast welding speed and relatively reduced heat input, the width of the heat affected zone is smaller than that of electrode arc welding, which is conductive to reducing welding deformation and preventing metal overheating. In addition, the welding surface is smooth and beautiful.

3. Improve the working conditions of welders: because the automation of the welding process is realized, the operation is relatively simple, and the arc burns under the flux layer without the harmful effect of the arc, so the mask can be omitted, and at the same time, less smoke and dust are emitted, so the working conditions of the welder are improved.

4. Save welding materials and electric energy: Due to the large welding seam depth, no or less grooves can be opened during submerged arc welding.
