JPS58151986A - Butt welding method of metallic strip by laser beam - Google Patents

Abstract

PURPOSE:To subject metallic strips to butt welding by a laser beam accurately, by disposing a shearing means for said strips and a welding means for the sheared groove surfaces separately and positioning both means under the same or equal conditions. CONSTITUTION:A shearing means 1 and a welding means 2 are disposed separately, and respective side guides 5a, 5b and 6a, 6b are disposed in such positions where the distances, sizes and positions from the common center C of the line are of the same conditions; at the same time, respective clamps 3a, 3b and 4a, 4b are also displayed laterally symmetrically with a shearing line S-S' and a weld line W-W' as centers. The metallic strips are fed from an arrow marked direction, and the side faces of the metallic strips are brought into contact with the guides 5a, 5b and are held with the clamps 3a, 3b, whereby the strips are positioned and are sheared. The strips are positioned and welded similarly in the welding means 2 as well. The line S-S' and the line W-W' are thus made parallel without fail, and the steel strips are welded surely by the ultra-thin laser light, too.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is superior to the #4FX metal bud O laser butting process and melting method, and it is highly recommended that the metal body is sheared to form a single point! !
llr manual cutting and this open arrow direction are matched and the laser matching means is provided separately.
Laser matching f# example method KO that can be matched to i
kru.

In general, butt welding equipment for metal strips is called a shear welder, and there is a built-in RVr in the shearing means, and the shearing means and the wall traveling torch head are connected to the welding edge extension. Many have a connected, integrated structure.

This structure is a structure that can be adopted when the vertical requirement is as long as TIG or MIQ melt, and when using a very thin thermal Im tube such as Laser light. This is inconvenient for m-building.

e) For the reason, 01~0.2m1C
) is used, so the tolerance value for the butt edge of the wrinkle bath becomes difficult, and the butt edge of the groove becomes extremely strict. Therefore, the tIl that determines whether or not to use a laser beam for the butting section is determined by (I) the longitudinal shear N of the butting portion, and (
21 Strict I of the butt part and the laser beam
II. There are several ways to ensure this mechanically.

The purpose of this project #4 is to solve the above-mentioned shortcomings, and after comparing the shearing means of the Kinshu Tei with the shearing force of the concrete K, #honor i! ! + 81 II K arrangement with 1iJ#
We propose a method for performing shearing and KIM contact by positioning the means and the means under the same or equivalent conditions.

9 below, I will explain about 1kK of Honyuzukata.

1st, the welding company metal emperor trims the etch and 7th,
There are many cases where there are slits, but even in such cases, the edges are completely K11. I! Let's say it is. In other words, when trimming and slitting, the partial release of the internal stress in the metal strip may be the cause, or the koji in the shape of the trim and slit may be the cause, as shown in Figure 1. The school has become a horizontal or meandering cram school.

On the other hand, in the shearing means, in order to produce one angle at between the shear @S ~ 8' and the etch E, when shearing %, each member Kt is forced to cut while pressing the guides 5a, 5b, and 1.6bK. (See 111-).

The value is the above-mentioned Jotai, Edge H (ZJ-1, Snake Kll)
Gives 41 strange shadows.

In addition, metal 11K often has shape distortion or difference in thickness, so the crank shape during shearing - 1 clamp e during welding

First, the ends are sheared 111r by the shearing means, and then the ends are welded one by one by the S* means. In this case, when shearing, the O-shaped mff1! The nose does not appear completely during jW, and the butt art oval wrinkles by laser light (! I! Attack).

In short, when determining the position using a shearing means, a side guide device using a welding means, or a clamp,
For example, gold II with one shearing means as shown in III#lJK

Positioned by clamps 31 and 3bK, sled 1! This means that the welding method cannot be used again when welding.

Therefore, in order to remove the dust, K is a shearing means.
By hand setting each guide by 1 m, each guide is arranged so that the distance, dimensions, and position from the center of the common line are the same, and each crank is also arranged with the same shear surface %ill*.

If the shearing means and the welding means are arranged separately in this way, the maintenance and inspection of the shearing means will be extremely easy.Furthermore, in both methods, the clamps, etc. in the nide guides can be arranged in relation to each other as described above. Since the metal 10 positioning shape 1 of the shearing means is
