Japan laser repair · welding machine

STL-150

For precision repair and welding, the traditional welding method is difficult to achieve !

Laser to achieve a precision repair and welding !

Only laser can be done to repair and welding !

Features

  • Operation is easy. high skill is not needed.
  • Heat input is low. There is no distortion, undercut, stress and pinhole occured.

  • Wire is melt completely into the base material, strength is very high.
  • With Ar gas protection, there is no oxidation occured on the welding point.
  • Possible to weld at bottom, inner wall, inside corner of deep narrow grooves and hole.
  • Possible to weld accurately with a few deposition. Finishing time and cost is reduced.
  • There is no nessesary to pre-heat and post-heat comparing with TIG welding.
  • Possible to weld wire to same material. No hardness changed, etch treatment is possible Possible to weld dissimilar metals.
  • Possible to weld almost metal, steel, Al, Cu, Ti, SUS, Au, etc.

Laser welding & Argon welding ( TIG )

Laser welding

Advantage :

① Simple operation

② Low heat input (no deformation, no stress, no undercut, no oxidation)

③ Able to carry out high-precision repair (to reduce the finishing time and cost)

④ For the narrow groove, the bottom of the hole, side, within the right angle can be patched

⑤ No preheating and insulation

Defect :

When the amount of repair is large, the repair speed is slower.

Argon welding( TIG )

Advantage :

① Quick fix

② Easy to operate in the field

Defect :

① Need superb welding technology

② Heat input large (easy to produce deformation, stress)

③ Prone to undercut

④ Welding more meat (finishing time and cost)

⑤ Narrow groove and the bottom of the hole • side of the repair more difficult

Application

  • Mold : Reparing Mold of Plastics, Rubber, Die-Casting.
  • Mechanical Part : Reparing Wearing, Scuffing of Mechanical Parts.
  • Welding Damege : Reparing the Undercut or Pinhole made by TIG.
  • Precision Part : Welding Electric Component, Sensor, Connector.
  • Dissimilar Metal : Welding Between Dissimilar Metals.
  • Sheet Metal : Welding Thin Metal Plate like Stainless.
  • Surface Treatment : Partial Reparing at the position of Thermal Spray, Plating, TD treatment etc.
