If tack welding is just for the purpose of holding the part in place then the welding tack size should be enough to hold it in place and should not exceed the final welding size. Spacing and number of tacks can vary depending on your requirement, but if enough space is available then try to avoid the consecutive tacks in the heat affected zone area of the previous welded tack. Usually spacing of 25 to 30mm is enough, increase the spacing as there is an increase in the leg size of the tack weld.
The tack welding size and spacing needed for a particular material thickness can vary, but a common guideline is to use tack welds that are approximately 1.5 times the material thickness. The spacing between tack welds should be around 3-4 times the material thickness, depending on the specific welding application and joint configuration. It's always important to refer to welding codes, standards, or consult with a welding engineer for specific recommendations.
For tack welding, the general guideline is to have tack weld sizes of 1.5 to 2 times the material thickness. The spacing between tack welds should be approximately 4 to 6 times the material thickness. However, these dimensions may vary depending on the specific welding project and material being used.
Tack welding is often used to hold materials in place before final welding. The thickness of the material being welded can affect the size and number of tack welds needed for proper positioning and alignment. Thicker materials may require more tack welds to prevent distortion or misalignment during final welding.

A number of factors go into this: base material thickness, joining material thickness, wire thickness, shielding gas composition, angle of weld, etc. The best way to determine this is to measure your material, then open your MIG welder, find the wire size of the spool, and read the chart inside of the MIG Welder door.
Post heating is generally recommended for carbon steel material above 19.05mm thickness to reduce the risk of cracking during welding and to promote better mechanical properties. The specific post-heating requirements may vary based on the material and welding process being used. It is best to consult the specific welding procedure specifications to determine the exact post-heating requirements for the application.
The thickness of the laser welding machine depends on the power of the laser generator inside the Laser Welding Machine, the thickness of the object to be welded. These two points are the most important.
The recommended amperage setting for welding stainless steel is typically between 50 to 90 amps, depending on the thickness of the material being welded. It is important to consult the welding machine's manual and adjust the settings accordingly for best results.
For welding 8 mm thickness metals, common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding (SMAW - Shielded Metal Arc Welding). The choice depends on the type of metal and specific requirements.
