The welding process used in water wall panels is typically TIG welding.

• TIG welding is commonly used for water wall panels due to its precision and clean welds

• TIG welding helps prevent contamination in the weld area, which is crucial for water wall panels

• Other welding processes like MIG welding or submerged arc welding may also be used depending on the specific requirements

Chain conveyors use chains to move products, while belt conveyors use belts.

• Chain conveyors are more durable and can handle heavier loads than belt conveyors.

• Belt conveyors are better suited for transporting smaller items and have a smoother operation.

• Chain conveyors are commonly used in industries such as automotive and steel, while belt conveyors are used in industries such as food processing and packaging.
