Covered electrode welding<\/strong>, also known as Shielded Metal Arc Welding (SMAW)<\/strong> or Manual Metal Arc (MMA) welding<\/strong>, is a welding process that uses an electrode coated with a flux to create an arc between the electrode and the workpiece. \u00a0<\/a><\/p>\n\n\n\n

Process Overview:<\/h3>\n\n\n\n
    \n
  1. Electrode:<\/strong> A metal rod coated with a flux material is used as an electrode. \u00a0 <\/a>1. How It Works: What is a flux in welding and what are the ingredients of fluxes used in the welding of Carbon Steels? | CWB Group <\/a><\/a><\/a><\/a>www.cwbgroup.org<\/a><\/a><\/li>\n\n\n\n
  2. Arc Initiation:<\/strong> An electric arc is struck between the electrode and the workpiece. \u00a0 <\/a>1. What is Arc Welding? – Definition and Process Types – TWI Global <\/a><\/a><\/a><\/a>www.twi-global.com<\/a><\/a><\/li>\n\n\n\n
  3. Shielding:<\/strong> The electrode coating melts, forming a protective gas shield around the weld pool. \u00a0 <\/a>1. Shielded metal arc welding – Wikipedia <\/a><\/a><\/a><\/a>en.wikipedia.org<\/a><\/a><\/li>\n\n\n\n
  4. Weld Formation:<\/strong> The heat from the arc melts the electrode and the base metal, forming a weld pool. \u00a0 <\/a>1. Arc Welding Fundamentals – Lincoln Electric <\/a><\/a><\/a><\/a>www.lincolnelectric.com<\/a><\/a><\/li>\n\n\n\n
  5. Slag Formation:<\/strong> The electrode coating forms a slag covering over the weld pool, protecting it from the atmosphere. \u00a0 <\/a>1. Everything You Should Know About Weld Slag (And Why) – Hobart Brothers <\/a><\/a><\/a><\/a>www.hobartbrothers.com<\/a><\/a><\/li>\n\n\n\n
  6. Cooling:<\/strong> The weld pool solidifies, and the slag is removed after cooling.<\/li>\n<\/ol>\n\n\n\n
