Abstract
The invention discloses a U-steel butt joint process. The U-steel butt joint process comprises the following steps that 1, lineation is conducted; 2, cutting is conducted, specifically, blanking is conducted through a semi-automatic flame cutting machine along lines, after blanking is conducted, 45-degree single V-shaped grooves are formed in the inner side surface of the U-steel through the semi-automatic flame cutting machine or a grinding machine, and cutting surfaces should be smooth, flat and free of notches; 3, assembling is conducted; 4, welding is conducted, specifically, gas shielded welding is adopted, the U-steel should be subjected to back-to-back spot welding in pairs before welding in order to reduce welding deformation, the groove sides on a wing plate are welded at first, and then the grooves in a ventral plate are welded; and after the groove sides are welded, the U-steel subjected to spot welding in pairs is opened, the back surface of the U-steel is subjected to gouging back chipping, then welding is continued, and the post-welding surplus height should be less than 2 mm; and 5, when the two pieces of U-steel are combined, full-length welding is required, and the butt joint clearance is required to be 500 mm or above. According to the U-steel butt joint process, the process is reasonable, the manufacturing cost is low, arrangement of all parameters is reasonable and coordinated, and the product quality and the production efficiency can be effectively improved.
Description
Technical field
The present invention relates to a kind of channel-section steel butt-joint process.
Background technology
Existing channel-section steel butt-joint process exists that procedure arrangement is unreasonable, operation is various, and technological parameter selects unreasonable, and the collocation of each technological parameter is unreasonable and operator's skill requirement is higher so that production cost is higher, product quality is on the low side, yield rate is not high.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved be to provide a kind of operation rationally, the channel-section steel butt-joint process of low cost of manufacture.
For achieving the above object, the invention provides
A kind of channel-section steel butt-joint process, comprises the steps:
1), line:
A) according to the length dimension after docking, line on the angle steel preparing docking, two requirements should be met before line:
A1) ensure that the minimum length of docking channel-section steel is greater than 500mm；
A2) length direction should leave the surplus of 2 ~ 3mm；
B) principle rule is that the line of cut on two wing plates of channel-section steel should be perpendicular to web, and on web, line of cut should angle at 45 °；
2), cutting: with semiautomatic flame cutting machine along line blanking, open 45 ° of single V-butts with semiautomatic flame cutting machine or abrasive machine at channel-section steel medial surface after blanking；Facet should be smooth, non-notch；
3), assembled:
Preparing assembled channel-section steel back-off on platform two before assembled, then adjust linearity and the gap of two channel-section steels, spot welding is fixed；
4), welding:
Employing gas shielded arc welding welds, for reducing welding deformation, should be spot-welded together back-to-back in pairs by channel-section steel before weldering, and first the groove side on weldering wing plate, then welds the groove of web, after groove side has been welded；Being opened into the channel-section steel to spot welding, back side gouge back chipping, then proceed to welding, postwelding reinforcement should be less than 2mm；
5) when, two channel-section steels are involutory, it is desirable to full weld, and butt joint gap requires at more than 500mm.
The invention has the beneficial effects as follows: operation of the present invention is reasonable, low cost of manufacture, each parameter collocation reasonable coordination, it is possible to be effectively improved product quality and production efficiency.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
A kind of channel-section steel butt-joint process, comprises the steps:
