1.0 Introduction
Shielded Metal Arc Welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.

🎮 Game 1: Master the Welding Bead
Draw a straight welding bead along the guideline before time runs out! Stay accurate for combo bonuses!
🎯 Tip: Maintain steady speed and accuracy for higher combo multipliers!
2.0 Objective
- To demonstrate some mostly used welding processes.
- To build a welded bead technique on a mild steel plate.
3.0 Apparatus
Equipment List:
- ⚡ Power Supply (17-40V, 120A) - AC, DCRP, or DCSP
- 🔧 Arc Welding Machine
- 🔩 Thin plates of mild steel (workpiece)

4.0 Method of Approach
Follow these steps carefully. Mark each step as complete as you finish it.
Safety Instructions
Welding is a potentially hazardous process.
To minimize injury risk, be aware of the hazards and use all required Personal Protective Equipment (PPE). The three major injury cases are:
1. Eye Damage
Caused by the intensely bright arc. Always use a welding face mask.
2. Molten Metal Burns
Hot slag and metal can cause severe burns. Wear safety gloves and protective clothing.
3. Conductive Burns
Direct contact with a freshly welded (and hot) workpiece can cause burns.
🎮 Game 2: Arc Striking Blitz
Strike all targets before time runs out! Chain hits for massive combo bonuses!
🎯 Tip: Hit targets quickly and accurately to maintain your combo!
Interactive Practice Zone
🎮 Game 3: PPE Speed Challenge
Drag each safety item onto the correct body zone before time runs out!
Drop the gear on the highlighted zones to equip your welder.
🎮 Game 4: Angle Master Challenge
Hold the electrode at the right travel angle while the joint progresses. Match the target angle!
Tip: Fillet welds love a 10°–15° travel angle.
