OK is the best, all-round, rutile electrode and it is relatively insensitive to rust or other surface impurities. It deposits smooth weld beads in all positions. Download our new Filler Metal Handbook - a helpful resource to welders and fabricators. This page digital book is your guide to all things filler metals, and .

This also promotes low sensitivity to surface impurities and contributes to smooth, sound welds. Square butt joints: Shield-Bright L X-tra was developed for the welding Type L stainless steel and also can be used for the other stainless steels including Types and L. Copper-coated, unalloyed wire for Submerged Arc and Electroslag Welding. This electrode can be used on X80 strain based and X A basic coated electrode for steels and castings with U. Choice of welding process:
Vertical and overhead welding often require an electrode one size larger in comparison to electrodes with other types of coating. Cellulose electrodes are extremely good for vertical-down welding. Basic electrodes are less likely to produce either hot cracks or cold cracks compared with other types of electrode.
The slag from basic electrodes has a lower melting point than that from rutile or acid electrodes. General information Unalloyed basic electrodes Rutile-basic. The conditions to be considered when choosing the correct electrode. The composition of the material to be welded when deciding a which types of welding alloy are usable and suitable b if preheating is favourable c if welding a buffer layer is necessary 2.
Working conditions 3. The table provides information about suitable electrodes and the different kinds of attack which must be taken into account. The working conditions for an object that is going to be repaired are often known. Machinability requirements Useful information when choosing the correct type of alloy 1.
General information Choose the correct OK electrodes. Type of wear 2. The recommended OK electrodes. Working conditions for the repaired workpiece a Type of wear: Environment a Corrosive or non-corrosive? For steel and cast iron weldments: Recommendations for the right choice of electrodes for joining dissimilar materials can be found in Figs 1 and 2 on the next page.
Conditions for welding a Is preheating possible or not? If it is not possible.
Short rules for choosing the correct type of weld metal alloy for hardfacing and cladding With regard to: Third hand choice Copper and copper-alloy All types of cast iron.

OK Tubrodur SAW OK Mn steel OK OK Autrod Joining Object Table 2. SAW Stress relief. High speed tools Hot bar shears steel Forging tools OK C steel and lowalloyed steel OK For this reason.
Choice of welding process: Short arc or spray arc The electrodes for gas metal arc welding listed in these pages are suitable for short arc welding in the smallest diameters and for spray arc welding in diameters 1. It is therefore often used. The higher the welding current. Moisture in the gas can produce porous welds. Short arc welding welding with short circuiting droplet transfer can be carried out in all positions and is the best process for welding sheet material approximately 0.
These gases are less expensive than those based on pure argon and can often be used with equally good results. Shielding gas for mild and low-alloy steels Carbon dioxide.
A further advantage of mixed gas is the higher quality. This is particularly important when welding aluminium and aluminium alloys. The shielding gases which are used must be of a purity suitable for welding. Welding technique The welding gun is normally held in the right hand.
Mixed gas. Other welding conditions may produce weld metal analyses and mechanical properties which differ from those given in the handbook. The cleaner the joint.
The mechanical properties are obtained according to the weldding conditions given in EN i. The arc voltage must be kept constant. The more impurities on the fusion faces.
As a general rule. General information General recommendations for Submerged Arc Welding 1. The fusion faces and the plate in the vicinity of the joint should be clean and dry. In tropical. High strength steel: Non-alloyed and low-alloyed steels Consumables are divided into three categories based on their tensile strength level: Normal strength steel: AWS and EN.
To ensure that valid information is used. H15 two-run welding submerged arc welded with one run from each side multi-run welding submerged arc or automatic gas-shielded arc welding semi-automatic.
