Welding information starts with material specification and condition before welding form and dimensions of the joint welding process to be employed type and specification of consumables Final heat treatment to perform following welding testing techniques required reference to non destructive testing requirements mechanical tests if any Welding defects and strength quality In order to prevent welding defects and improve quality it is important to select materials and processes suitable for the application in the welding design phase Even if the design is appropriate however defects produced during welding will have a major influence on quality The purpose of the Welding Handbook for maritime welders is to provide guidance in modern welding and related processes and to provide the welder with a source of practical information on the right solution to specific onboard welding problems Experience gained from user contact and welding training of crewmembers showed thatWelding symbols provide the means of placing complete welding information on drawings The joint is the basis of reference for welding symbols The reference line of the welding symbol is used to designate the type of weld to be made its location dimensions extent contour and other supplementary information welding coordinator s about the relevant standards regulations and specifications to be observed • Check the ability of the welding coordinator s to detect and assess defects to instruct repairs and to know how to avoid defects This publication has been prepared to provide guidance on how toprovide additional information to the welder concerning variables which are not usually addressed by the Welding Procedures The direction provided by the Welding Procedure Specification and the “Mandatory Practices” in this document constitute the minimum requirements for code welding The above requirements may not be changedELECTRODE PART NUMBER CHART ELECTRODE DESCRIPTIONS TYPE Mild Steel Current AC/DC All position electrode Use when you are unable to prepare a welding surface Its deep penetration allows welds through rust scale oil and dirt TYPE Mild Steel Current AC/DC All position electrode Best used with clean or prepared welding surface Most people have seen or are aware of welding It is the process of joining two metal parts However owing to its extensive use providing information about the type and size of the weld through symbols becomes essential We at ScienceStruck have provided a comprehensive welding symbols chart that will help you communicate better with your welder or fabricator ►V PRODUCT CONSTRUCTION Conductor 6 AWG through kcmil fully annealed stranded bare copper Class K Jacket Premium grade 90ºC EPDM black or red Temperature range 40ºC to ºC APPLICATIONS For use with secondary voltage resistance welding leads and power supply applications not exceeding V AC FEATURES
