Abstract

The invention discloses a portal welding process, and relates to the field of steel welding. The portal welding process comprises the following steps: (1) steel beam fixing: a steel beam needed to be welded is positioned on a support frame of a portal welding machine; (2) welding torch positioning: the position of a welding torch is shifted, so that the welding torch forwards moves along a welding line until the welding torch is positioned above a welding starting point; (3) cardinal number adjustment: the current and the voltage of the portal welding machine are adjusted according to a welding thickness; (4) steel beam welding: the welding torch is sunk, so that a welding wire is aligned to a welding line, and the welding is started; (5) repeated welding inspection: the welding torch is shifted again to the welding starting point; the condition of the welding line is checked; and the secondary welding is performed; and (6) cooling: a welded reinforcement is cooled at normal temperature. The process adopts the portal welding machine to weld, and is mainly applied to H profile steel. The spot welding is performed for the H profile steel before welding, so that the steel beam cannot generate the deviation phenomenon in the welding process.

(2), location welding torch: the position of mobile welding torch so that welding torch is along sealing wire reach until welding torch is positioned at the top of weld starting point;
(3), radix is regulated: according to the electric current of the thickness adjusted gantry welding machine of welding and voltage;
(4), welded steel beam: sunk by welding torch so that welding wire alignment weld seam, starts power supply, starts welding, move until welding terminal during welding after sealing wire, and welding torch rises;
(5), check multiple weldering: welding torch is moved on to again welding starting point, checks the situation of weld seam, adjust voltage x current, carry out second time welding;
(6), cooling: the reinforcing bar welded is cooled down at normal temperatures.
Preferably, after the fixing girder steel of described step (1), in institute's weld inspection and clear up dirt, oils and fats.
Preferably, in described step (3), the range of accommodation of electric current is 300-1000A, and the range of accommodation of voltage is 20-60V, and electric current often increases 100A, and voltage increases 1-2V.
Preferably, described step (4) in the process of welded steel beam, the welding slag of continuous trimming both sides.
Preferably, in described step (6) in cooling procedure after room temperature cools down 5-10 minute, cold water can be adopted to cool down.
Preferably, after described step (6) cooling, is polished in the commissure of girder steel, until smooth.
Provide the benefit that: this technique is to adopt gantry welding machine to weld, and is mainly used for H profile steel.H profile steel first carries out spot welding before welding so that girder steel does not have the phenomenon of skew in welding process.Gantry welding machine is when welding compared to general bonding machine, and it welds distance, and welding is stable, is especially suitable for girder steel etc..Adopt room temperature cooling can keep the mechanical property of girder steel after welding, just cool down with cold water afterwards, be acceleration rate of cooling under the premise of the mechanical property having ensured girder steel.
