for mig welding spatter can be reduced by amp, voltage and wire speed adjustment. check shielding gas. stick welding check the recommended voltage, amps and application for the rod you are using keep your arc short. tig welding, be sure you are using the proper tungsten, and shielding gas and filler rod for the metal you are welding, don't dip the tungsten. make sure the metal you are welding is clean .
Sub arc welding is a process in which the welding actually occurs while submerged under a layer of flux. Not only does this prevent oxygen from entering the weld and thus porosity, but it also keeps the dangerous arc from sputtering and spattering from the weld.
Plasma arc welding can weld almost any commonly used metal. It is not limited to magnetic metals, they only need to conduct electricity.
saw stands for suberged arc welding, where the weld is submerged underneath the flux
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.

Sub arc welding is a process in which the welding actually occurs while submerged under a layer of flux. Not only does this prevent oxygen from entering the weld and thus porosity, but it also keeps the dangerous arc from sputtering and spattering from the weld.
why is it important only to strike the arc in the weld joint
Too long an arc length allows the arc to wander creating a poorly shaped weld. The slag is usually too thin and can allow Oxygen in the air to attack the molten puddle which causes Porosity in the weld. Too short an arc length buries the slag and creates less heat which traps the slag and impurities. Keep in mind that electrode coatings help determine the correct arc length.
You can arc weld & then the flux will be in the rod.
Partially by the smoke that is produced. This helps to keep the surrounding air away from the puddle. Mostly by the slag that covers the weld almost immediately as the arc moves on.

Arc shielding in Shielded Metal Arc Welding (SMAW) involves the use of a consumable electrode that produces a protective gas and slag when it melts. This shielding effect protects the weld pool from atmospheric contamination, such as oxygen and nitrogen, which can weaken the weld. The electrode coating generates gases and forms a molten slag that covers the weld area, stabilizing the arc and enhancing the quality of the weld. Proper arc shielding is crucial for achieving strong, defect-free welds in various materials.
Providing a shield of gases during arc welding is essential to protect the weld from atmospheric contamination such as oxygen and nitrogen. These gases can react with the molten metal, leading to defects in the weld like porosity, cracking, and reduced strength. Shielding gases help to create a stable arc, protect the molten weld pool, and improve the overall quality and integrity of the weld.

It can be controlled by connecting the work lead to tha end of tha weld joint and than welding away from the work leadThe ARC blow can be controlled by connecting the work lead to the end of the weld join. Then you will have to weld away from the work lead.
Plasma arc welding can weld almost any commonly used metal. It is not limited to magnetic metals, they only need to conduct electricity.
Barely, 24v or36v in series is better
