Team Work - We look upon ourselves as an extension to your maintenance department or workshop. We try to understand your needs and adapt ourselves accordingly. We hope that by working together we can help improve the performance of your maintenance department and ultimately save you money.
团队合作 - 我们将自己视为客户维护部门或车间的延伸。我们努力了解客户的需求,并相应地调整自己。我们希望通过共同努力,可以帮助客户提高维护部门的绩效,并最终为客户节省资金。
Multi-Skilled Fitters - During a recent survey in the U.S.A., it was discovered that over 50% of all weld failures were due to operator error. This is not to say that the operators were incompetent through any fault of their own; what it did highlight was that with the present, more cost effective trend towards multi-skilled fitters, the operator may not have the specialised knowledge needed to tackle the problem at hand.
多技能修理工 - 在美国最近的一次调查中,发现超过50%的焊接故障是由焊工出错造成的。这并不是说焊工因自身的任何过错而无能;它所强调的是,在目前多技能修理工更具成本效益的趋势下,传统焊工可能不具备解决手头问题所需的专业知识。
To help overcome these difficulties we offer 2 on site training courses. Both can be tailored to meet the individual requirements of your company to ensure maximum benefits are obtained.
为了帮助克服这些困难,我们可提供两个现场培训课程。两者都可以根据客户的具体要求进行定制,以确保获得满意效果。
1. Basic Manual Metal Arc - This course is run by a Lloyds qualified maintenance welder it is designed to improve the delegates basic welding techniques. It will ensure they gain confidence in their own ability and in turn improve their efficiency and productivity within the department. The main areas to be covered both practically and theoretically are as follows:
基本手动金属电弧焊 - 本课程由经验丰富的维护焊工(高级技师)负责,旨在提
高学员的基本焊接技术。这将确保他们对自己的能力有信心,进而提高部门
内的效率和生产力。在实践和理论上需要涵盖的主要领域如下:
(i) Striking the Electrode 引弧
(ii) Horizontal Welding (including length and angle of arc) 平焊(包括弧长和弧角)
(iii) Vertical Down Hand welding 垂直向下焊接
(iv) Types of welds 焊缝类型
(v) Types of joints 接头类型
(vi) Electrode Classification 焊材分类
(vii) Health & Safety Procedures 健康与安全程序
2. Applications and Basic Theory - This course is run by a qualified metallurgist. It is designed to increase the delegates knowledge of potential applications within your factory and how to perform them ensuring that cost savings are being made.
应用和基础理论 - 本课程由资深焊接专家负责。它旨在增加学员对工厂内潜在应用程序的了解,以及如何执行这些应用程序,以确保节约成本。
To ensure that delegates can relate all training to your own companies needs, both courses can be held at your company premises, usually lasting one or two full day. If requested both courses can be run simultaneously.
为了确保学员能够将所有培训与公司需求联系起来,这两门课程都可在客户公司举办,通常持续一到两天。如果有要求,两门课程可以同时进行。
