I use to run one a bit last year at a customer. I think this is a great site enjoy reading the post.
I had to hand write g code for the first 3 months till we actually decided on software that was fun but i think it has been a valuable lesson.we happened to be slow at the time and just worked on the plant for about 3 months so i had plenty of time to get the hang of it.i use fabriwin 2013 to do all the nesting and program writing now and create or modify parts when needed.does anyone else do all that as the operator?any way i have been running it for about a year now.just wanted to introduce my self maybe i can help someone out there also learn some new stuff.
I had 3 days training when the machine was installed about one in reality the rest was the install lol i have all the books with the machine and internet access at work so i was lucky there. I just wish it could be condensed onto one site. No one to teach accept the internet lol which has done a fairly good job. I got the job as the laser operator this is the only laser we have and i had to learn everything on my own did not no one thing about g code such a newb. little back ground my company purchased a used amada 24kw laser. Our powder coating has pass through 1000hrs salt spray test as per ASTM B113.Just looking to trade tips or tricks with any laser operators out there. We stock a wide range of colours and finishes including satin, gloss, matt, leatherette, texture and plasticoat finish. The skilled painters are also able to provide perfect finishes by hand on intricate work. The quality is checked continuously with a paint thickness, scratch and cure test. We can accommodate parts up to 1400mm deep, 2500mm long and 600mm wide. The coating is typically applied Electrostatically and is then cured under heat to allow it to flow and form a skin.
The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. ¤ Powder Coating - Powder coating is a type of coating that is applied as a free-flowing dry powder. Dust particles, oil, welding scales, metal oxide and rust on surface of metal gets removed in pre-treatment process and Thin layer of Phosphate gets form on surface which prevent metal for getting Rusty in Future and improves bonding of powder with metal. Material should pass through Pre-treatment process before powder coating. ¤ Pre-treatment - We have 11 tanks Automatic pre-treatment process with hot air Drier. Studs have a necked down, un-threaded area for the same purpose. Weld nuts generally have a flange with small nubs that melt to form the weld. The bolts may be automatically fed into the spot welder. Stud welding is a form of spot welding where a bolt or specially formed nut is welded onto another metal part.
This is accomplished through torch manipulation by the welder. The metal puddle will travel towards where the metal is the hottest. Usually, more metal is added to the puddle as it is moved along by means of dipping metal from a welding rod or filler rod into the molten metal puddle. The puddle is moved along the path where the weld bead is desired. The flame is applied to the base metal and held until a small puddle of molten metal is formed. Weld strength is significantly lower than with other welding methods, making the process suitable for only certain applications on ferrous metals. The advantages of the method include efficient energy use, limited work piece deformation, and no required filler materials.
Two electrodes are simultaneously used to clamp the metal sheets together and to pass current through the sheets. The process is generally limited to welding ferrous materials.Ī resistance welding method used to join overlapping metal sheets of up to 3 mm thick. Electric current is used to strike an arc between the base material and consumable electrode rod, which is made of steel and is covered with a flux that protects the weld area from oxidation and contamination by producing CO 2 gas during the welding process. The process can be applied to a wide variety of metals, both ferrous and non-ferrous.Īlso known as stick welding. GMAW is well suited to production welding. The equipment required to perform the GMAW process is more complex and expensive than that required for SMAW, and requires a more complex setup procedure. Since the electrode is continuous, welding speeds are greater for GMAW than for SMAW. It is a semi-automatic or automatic process that uses a continuous wire feed as an electrode and an inert or semi-inert gas mixture to protect the weld from contamination.
