The lefthand scrolling photos: Critical step in production from steel strip plates to finished T H Beam, with Wuxi JACK 3 in 1 Vertical H Beam Welding Machine
1. Raw Material Loading: 2 pieces of long narrow steel strips Flange and web) are loaded onto machine infeed conveyor;
2. First, T Beam Fabrication: The loaded flange and web are fit up/ clamped/ welded/ straightened into T Beam, and sent out of machine by way of outfeed conveyor;
1) The 2nd piece of strip plate is put onto infeed roller table of machine;
2) The first step fabricated T Beam is flipped 180°, and loaded onto infeed roller table of machine. Web edge of T Beam coincides with middle line of the 2nd piece of flange;
3) In this way, workpiece is fit up into H Beam structure, got strengthened with hydraulic manipulators, being deployed along infeed conveyor;
1) In this way, H Beam is assembled/ welded, and straightened into finished workpiece;
2) Summing up, workpieces pass through machine in 3 steps of: Fitting up (Assembly)/ welding/ straightening in a row;
3) The entire process of T Beam and H Beam fabrication are in position of vertical. This is machine name got from.
1) Summary: Cross section of H Beam produced from PHJ models can be both symmetric, and asymmetric;
2) Welding Technique:
a) Automatic large current SAW (Submerged arc welding) in flat position;
b) Welding consumables: Φ2.5mm ~ Φ4mm solid wire and welding flux, for Single Arc mode; Φ1.6mm solid wire for Twin Arc/ Tandem Arc;
This is the main difference between PHJ and ZHJ series: In PHJ models, fitting up on flanges with web is in semi-automatic mode: One side of H Beam is driven with oil cylinders, and the other side is pushed manually by means of turning handwheel;
1) Finished Workpieces: ZHJ series is the later product following PHJ series. It is specifically focused on fabricating symmetric cross section T H Beam. This kind of H Beam has majority use in steel structure field;
a) ZHJ series also adopts with flat position SAW (Submerged arc Welding), with one time pass of welding on H Beam;
b) So, finished welding seam is smaller than H Beam produced from H Beam Gantry Welding Machine, which has multiple passes of 45° fillet SAW Welding;
3) Assembly Technique: Fitting up flanges with web is fully automatic and slightly quicker than PHJ: Both sides of H Beam are in phase hydraulic drive and leadscrew transmission;
1) Background: Below hand making sketch gives example on small H Beam to be produced from ZHJ10 model machine: Its flange and web thickness is half of H Beams delivered from PHJ15 and ZHJ15, around 15mm to 20mm: (Fig.2)
2) Welding Technique:
This is primary difference between small model and conventional models: Small models adopt with CO2 Gas Shielded GMAW welding, instead of large welding current SAW;
3) Assembly Technique:
This function unit works in the exact same manner as ZHJ series: H Beam is assembled with automatic control in phase;
4) Example Small Models: ZHJ10 and ZHJ12, for producing max. H Beam height of 1,000mm and 1,200mm respectively.
