yes
Short answer: No. Long answer: Welding stainless directly to titanium results in an unusable weld. If you have access to an electron beam welder (they cost millions and they're the size of a house) you can design a joint with a piece of vanadium between the two other metals.
A welder utilizes technical drawings to determine what type of joint he must weld , joint preparation, where on the joint the weld must be placed, the size of the weld, and so on . Certain structures require this specific information , in order to be safe , sound , etc.

Preparation: Ensure the 4140 steel workpiece is clean and free of any contaminants, rust, or scale. Place the workpiece in a heat-resistant container or fixture that allows for uniform heating and cooling. Heating: Preheat the furnace or kiln to the annealing temperature, which is typically around 1600°F (871°C) for 4140 steel. Insert the workpiece into the preheated furnace. Make sure it is supported and positioned to ensure even heating. Allow the steel to soak at the annealing temperature for a sufficient amount of time to ensure uniform heating. The soak time may vary but can be in the range of 1 to 2 hours.
In order to weld pieces of 6mm steel you can use any type of welder. Depending on how strong and how pretty the weld needs to be will determine the type of welder you choose.
about 2mm mild steel max
Tig, mig , or If you are as good as me stick welding will all work
can weld aluminium with a mig or tig welder
SP welder means Structural purpose welder.
The type of welder is dependant on what you want to weld with the machine. Welding heavy steel will take a bigger machine than one that is used for light metal.
arch welding is a more stable form of welding. it get hotter and creates a stronger bond
Weld
Yes, you can weld steel to steel. You can use steel welding rod.
yes
Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
