Description
Technical field
The present invention relates to a kind of internal welding machine field, more particularly to a kind of pipeline gas shielded arc welding formula internal welding machine.
Background technology
Internal welding machine is mainly used in the pipeline constructions such as petrochemical industry, electric power, coal, water delivery, and major function is to complete two pipes
The group pair in road and internal root bead.
Existing interior bonding machine is as shown in figure 1, main by forebay 1, line-up clamp 13, rotating disk 3, welding unit 4, tensioner
Mechanism 5, middle frame 6, floating spring mechanism 7, drive mechanism 8, afer bay 9, braking mechanism 10 and gas tank 12 are constituted.Above-mentioned shows
Though the interior bonding machine having can provide user one with good welding machine effect, really with progressive, when actually used
