How to start manufacturing of welding electrodes?

Welding Electrodes are commonly used consumables in industries where welding is required. The welding electrodes are used in the construction and manufacturing sector where metal welding is done. The welding electrode business has some advantages associated with it. The setup and manufacturing process is easy, the demand ever increasing, and the raw material required and be procured easily. Also, the higher the quality of the product manufactured, the more premium can be charged. Welding is a critical aspect in construction and developmental, and repair work. The manufacturing of welding electrodes requires the preparation of core wire and rod for welding electrodes, preparation of the dry and wet mix, application of coating material by extrusion and final baking of coated electrodes. The demand for welding electrodes is increasing in line with industrial production in all sectors. There is good scope for this fast-consumable item to be produced in the small-scale sector.The types of welding electrodes in the Indian market today are

• Mild Steel welding rod
• Stainless steel welding rod
• Cast iron welding rod
• Tungsten welding rod
• Hard facing rod
• Plastic welding rod
• Gas rod
• Carbon electrode
• Alloy rods

Although the raw material for electrodes varies depending on the product, the manufacturing of welding electrodes remains almost the same. The difference lies in the material used for coating and the metal used. Factors like tensile strength, corrosion resistance and weldability of the electrodes are some of the critical qualities a buyer looks for in this product and readily pays a premium for quality products. While some welding electrodes, like mild-steel electrodes, go for 500-2000 rupees per kg, specific electrodes such as tungsten welding rods and alloy rods made with Ni-Cu alloy that provide a weld metal with good corrosion resistance to seawater and flue gases can retail for even more. Let’s understand the stages in the setup of this business.

Cost: Depending on the availability of capital and resources, fully automatic or semi-automatic manufacturing of welding electrodes can be set up. Depending on the installed capacity, the cost of setting up the plant can be anywhere from 20 lakhs and upwards.

Stages in setting up manufacturing of Welding Electrodes

To set up your own welding electrode manufacturing unit, you need to do extensive research about the manufacturing of welding electrodes. There are many manufacturers in the country with a variety of production lines manufacturing all kinds of welding electrodes. However, to start this business, thorough research of the latest technology, present market demand and analysis of quality raw materials and their suppliers is required. Following are the stages in setting up a welding electrode business.

Preparing a Business Plan

A sound business plan must be the foundation of the manufacturing of welding electrodes. The site selection and detailing facts, including the process, capacity, quality, marketing, etc., must be taken care of.

Sourcing of machinery and workforce

As most of the manufacturing plants are semi-automatic or fully automatic, the nature of the production will depend on the machinery installed by the entrepreneur. Also, as this manufacturing of welding electrodes is not labour-intensive, a small number of skilled and trained employees can seamlessly manage the facility.

Testing of the product

Many manufacturing units have their in-house labs to test the quality and durability of welds as the manufacturer is mandated by law to assure quality factors like tensile strength and longevity of welds. For assessing the mechanical properties of the welded metal, and the usability of an electrode for a particular welding position, the electrodes manufactured in a facility are subjected to the following tests.

Initial Tests:  These are qualification or proving tests for a particular type of welding electrode manufactured with a certain standard of basic material and certain production conditions. The modified type of welding electrode must be subjected to the initial tests. It must be implicit in the manufacturer’s certificate that the electrodes certified by him conform to any one classification and satisfy all test requirements prescribed for initial tests for that particular classification.

Periodic check tests: These comprise a few of the tests selected from among the initial tests, which are repeated at intervals to provide evidence that the electrodes currently being produced possess the properties proved in the initial tests.

Production control tests: Using a suitable control system, the manufacturer must ensure that the composition and quality of all the electrodes currently produced are similar to those subjected to the initial tests.

Licences and Authorisation needed forManufacturing Welding Electrode

Licences and Documents required for starting the manufacturing of welding electrodes are as follows.

Consent NOC: As electrode manufacturing units are mainly air polluting, they have a Pollution Index (PI) normalised to 43.75. The manufacturing of welding electrodes has been categorised as an orange-category industry from the green category by the CPCB recently. The manufacturing units, therefore, must apply to their respective Pollution Control Boards (SPCBs) / Pollution Control Committees (PCCs) for the issuance of this No Objection Certificate. The Pollution Board will scrutinize the submitted documents, process the application on standard parameters, and initially issue a Consent to Establish (CTE). Subsequently, a Consent to Operate (CTO) will be issued after the successful completion of a site inspection. Before site inspection, all required pollution control measures must be installed.
