How to Weld Channel Letters


laser welding machine samples how to weld channel letters

As we know, to make complete 3D channel letters, we need to have at least three machines at the ready: one channel letter bending machine for the sidewall, one laser cutting machine for the steel panel, and lastly, the one machine that we will be discussing in this article: the handheld fiber laser welding machine which is capable of welding any kind of metal letters. The real all-in-one metal channel letter laser welding machine.

It breaks the limitations of the Yag laser-welding machine on materials because of its power and firmness of the finish, which makes it the best machine for welding your aluminum channel letters.

How does fiber laser welding work?

Since the fiber handheld laser welding machine can release a high energy, high density laser beam as a the heat sources on the metal surface during operation, it enables more efficient and precise welding than traditional welding. The high precision laser beam positioning makes the welding position free from any deviation, and the adjustable laser power makes the welded parts less prone to weld through, burned edges and other problems.

As is known to all, stainless steel or iron channel letters is the easiest to be welded by the traditional YAG laser welding, but the YAG welding or TIG/MIG welder on welding aluminum is still not strong enough or simply can not be welded, because aluminum is a highly reflective material, so the emergence of fiber laser welding technology to solve the problem of aluminum channel letter welding, not only can be welded aluminum letters can also be welded copper letter and other highly reflective materials. It is worth mentioning that the application of wobble welding head can achieve a maximum of 5mm wide seam welding, in addition to the additional automatic wire feeder filler welding, making the welded workpiece more solid.

What are the advantages of the handheld fiber laser welding machine? How to weld channel letters?

  1. Widely used in welding and forming different sheet metal pieces, ad signs, commercial kitchen equipment like stoves and food carts as well as windows, frames, metal furniture, lamp covers, power cases, fire boxes, pipes and so much more.
  2. Well-known fiber laser source applied to give it a longer service life and high performance, high photo-electronic conversion efficiency all with low maintenance and easy operation.
  3. Compact design and built-in water-cooling system to help minimize its footprint and ensure the greatest mobility.
  4. Choose from 1000W, 1500W, 2000W and 3000W to meet the different demands for welding depth and efficiency.
  5. Standard water-cooled welding gun support shield gas and optional wobble welding gun that can cover a 4mm-sized welding spot, allowing a wider seam or rough edge.
  6. Nice smooth finishing, 24-hours continuous welding and free polishing included.
