[0013] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, an adjustable welding tool comprises a movable base 1, wherein the four lower corners of the movable base 1 are respectively fixedly connected with universal movable wheels 2; and the upper rear left and right sides of the movable base 1 are respectively fixedly connected with brackets 3.

[0014] One of the adjustable welding tools also includes a self-centering clamping assembly 4, and the self-centering clamping assembly 4 is respectively fixedly connected to the front upper side of the bracket 3, which is conducive to achieving the effect of self-centering and fixing the pipe workpiece, and can make the pipe workpiece coaxially arranged after clamping, so as to facilitate the operator to weld the pipe workpiece, and is more convenient to use.

[0015] In this embodiment, combined with the Figure 2 and attached Figure 3As shown, the self-centering clamping assembly 4 includes a fixed plate 40, and through grooves are respectively provided on the front and rear sides of the middle part of the fixed plate 40, and sliders 41 are slidably arranged on the inner sides of the through grooves; the upper part of the slider 41 is fixedly connected with a clamping block 42, and the lower part of the clamping block 42 is slidably arranged on the front and rear sides of the upper part of the fixed plate 40; the lower middle part of the slider 41 is fixedly connected with an inverted U-shaped mounting seat 43; the lower middle part of the fixed plate 40 is longitudinally fixedly connected with a fixed sleeve 44, and the interior of the fixed sleeve 44 is slidably arranged with a telescopic Rod 45; a hand-tightening bolt 46 is threadedly connected to the opening on the lower right side of the fixing sleeve 44, and the fixing sleeve 44 is fastened and connected to the telescopic rod 45 through the hand-tightening bolt 46; the lower end of the telescopic rod 45 is fixedly connected to an H-shaped mounting seat 47, and the middle front side and the middle rear side of the H-shaped mounting seat 47 are respectively axially connected with connecting rods 48, wherein the upper ends of the connecting rods 48 are respectively axially connected to the middle and lower sides of the inverted U-shaped mounting seat 43; an inverted T-shaped operating rod 49 is fixedly connected to the lower middle part of the H-shaped mounting seat 47; V-shaped grooves are respectively provided on the upper inner part of the clamping block 42.

[0016] In this embodiment, specifically, the rear portion of the fixing plate 40 is fixedly connected to the front upper side of the bracket 3 .
