Abstract
The invention discloses a kind of H steel welding technologies, the first step keeps flat lower plate, and the lower side of riser is disposed vertically along the upper side of lower plate along straight line；Second step, interval spot welding is carried out in the lower side of riser along the welding seam to be welded and upper side of lower plate between；H steel welding technologies of the invention, solve the problems, such as that the weld seam that presently, there are is uneven, overcome the shortcoming for being susceptible to displacement between the adjacent two boards of H steel to be welded in welding.
Description
Technical field
The present invention relates to a kind of welding procedure of shaped steel.
Background technology
H steel is made up of three blocks of steel plates, and upper and lower two blocks of steel plates are parallel to each other, and one piece of middle riser is vertically stood between upper and lower two blocks of steel plates, and vertical with upper and lower two blocks of steel plates, and four weld seams to be welded are constituted between the lower edges of riser and upper and lower two blocks of steel plates.During present welded H steel, usually using riser is buttressed by hand, manually ensure that weld seam does not offset predetermined weld seam.But because people helps for a long time, it is certain to make be moved between steel plate, so that weld seam greatly deviates from predetermined position, even bend, because the H steel capital has several meters long, the product after deformation cannot be used at all, can not meet the depth of parallelism to H steel, and between middle riser and upper lower steel plate perpendicularity requirement, can only scrap.It is more long additionally, due to weld seam, first weld
Local temperature it is high, the local temperature welded afterwards is low, and the steel plate both sides temperature at place to be welded is different, and commissure to be welded can be made to produce slight displacement, even distort, and riser left and right distortion or vertically can bend up or down.Product quality is influenceed very much, production efficiency is also very low.
The content of the invention
It is an object of the invention to provide a kind of H steel welding technologies, it is ensured that the linearity of welded seam, weld seam is subjected to displacement in preventing welding, or even the sheet material for welding bends and causes weld seam to bend therewith.
The technical scheme is that：
H steel welding technologies, the first step prepares three block length square plates, respectively upper plate, lower plate and riser, and riser is the steel plate being vertically welded between upper plate, lower plate, and lower plate is kept flat, and the lower side of riser is disposed vertically along the upper side of lower plate along straight line
；
Second step, interval spot welding is carried out in the lower side of riser along the welding seam to be welded and upper side of lower plate between
；
3rd step, is inclined with sway brace and is placed on the upper side of the side side of riser and lower plate, by sway brace two ends difference
It is welded on the upper side of the side of riser and lower plate
；
4th step, full weld is carried out by the weld seam between the lower side edge of riser and the upper side of lower plate
；
5th step, removes sway brace；
6th step, three welding seams to be welded to riser and lower plate and upper plate repeat the first to five step
；
7th step, welding is completed.
The lower side of riser is placed along the upper side central axis of lower plate in the first step.
Also needed to weld cleaning welding slag in 7th step.
H steel welding technologies of the invention, solve the problems, such as that the weld seam that presently, there are is uneven, overcome the shortcoming for being susceptible to displacement between the adjacent two boards of H steel to be welded in welding.Present invention sway brace first fixes riser and upper plate or lower plate, then butt welding seam welding again, and the position during this between riser and upper plate or lower plate is fixed, will not be caused due to welding
Commissure it is uneven in temperature and produce slight displacement, distort weld seam, influence welding quality and attractive in appearance is also avoided because, due to the artificial larger displacement helped two blocks of steel plates unstable and the sheet material of commissure two is produced, weld seam is uneven in welding or bending.
Specific embodiment
H steel welding technologies of the present invention, the first step prepares three block length square plates, respectively upper plate, lower plate and riser, and riser is the steel plate being vertically welded between upper plate, lower plate, and lower plate is kept flat, and the lower side of riser is disposed vertically along the upper side of lower plate along straight line
；
Second step, interval spot welding is carried out in the lower side of riser along the welding seam to be welded and upper side of lower plate between
；
3rd step, is inclined with sway brace and is placed on the upper side of the side side of riser and lower plate, by sway brace two ends difference
It is welded on the upper side of the side of riser and lower plate
；
4th step, full weld is carried out by the weld seam between the lower side edge of riser and the upper side of lower plate
；
5th step, removes sway brace；
6th step, three welding seams to be welded to riser and lower plate and upper plate repeat the first to five step
；
7th step, welding is completed.
The lower side of riser is placed along the upper side central axis of lower plate in the first step.
Also needed to weld cleaning welding slag in 7th step.
