Stick welding, which is also known as shielded metal arc welding (SMAW), is among the oldest and the most versatile forms of welding. It requires more than one electric arc to melt the metal and join the parts together. This process is widely adapted in many sectors including manufacturing, shipbuilding, and civil engineering. To become an SMAW technician, one needs to have a blend of firm educational foundation and technical proficiency.
As we have discussed, shielding metal arc welding is among the popular welding types. To become a proficient welder in this field, one needs to understand the process first.
1. Arc Initiation: An electric current passed between the electrode and the base metal initiates the arc between the two.
2. Melting of Metal: The high temperature arc melts both the workpiece and consumable electrode.
3. Filler Metal Deposition: As the electrode melts, molten filler metal is provided to bridge the gap between the parts, if any.
4. Shielding Gas: It embeds a flux coating at the tip of the electrode which in turn gets transformed to gas during operation, thus protecting the weld pool from contact with air.
5. Slag Formation: The flux also forms a type of slag that holds on the molten weld metal to prevent exposure to oxygen.
6. Once the molten metal cools after switching off the arc, solidification takes place and a weld joint is formed.
As an aspiring technician, you might be wondering that there are different types of welding procedures then what makes shielding metal arc welding the most popular among them. Here are some of the advantages of SMAW that makes it a popular type among all.
Everything comes with certain challenges. To get the most out of welding training programs, technicians should have a basic understanding of some limitations surrounding SMAW welding type.
As we have discussed the pros and cons of shielded metal arc welding, one needs to overcome challenges to become an SMAW technician. For this, one needs to have a solid grasp of welding procedures and training.
In order to become a skilled SMAW technician, the following welder requirements need to be undertaken:
Typically, a minimum of secondary education or its equivalent is required. Some companies, however, may prefer a candidate with an education from welding tech schools or vocational training colleges.
Attend a trade school, community college, or vocational school to take a course in welding. These classes provide students with hands-on training in various types of welding including SMAW.
Apart from fulfilling welding education requirements, try to get some practical experience through apprenticeships, internships, or entry-level positions that involve welding.
Being qualified in welding will enhance your prospects and employability. There are several certifications including the Certified Welder (CW) and Certified Welding Inspector (CWI) offered by the American Welding Society (AWS).
In order to promote swiftness, steadiness, and the quality of their welding projects, one needs to practice and refine welding techniques consistently.
Be familiar with new welding technologies, practices, and regulations coming into the market. Also, observe the instructions on health and safety. The use of the appropriate gear and procedures must come first at all times.
To become an SMAW technician, one must acquire both mental and physical skills. An aspiring welding technician should be in good physical shape with the ability to operate heavy machines, bend and twist in difficult positions, and lift when necessary. Secondly, he/she should have good hand-eye coordination in order to manipulate the welding sticks appropriately. Thirdly, a SMAW technician should be equipped with critical thinking skills in order to troubleshoot and repair any defects when welding. By following these pointers and acquiring the necessary skills, one can be a SMAW technician and play an effective role in many sectors.
