GTAW mistake,welder dont know

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld.and its specified to meet strict aesthetic, structural, or code or standard requirements.

for the popular of Gas tungsten arc welding in the world,some people can master the principle,for its process is complex,it can not see by all people include some welders.now,by the post about the common gas tungsten arc welding mistakes based on what i write,we can prevent some gas tungsten arc welding mistakes form operating.

ok,let's see the mistakes in gas tungsten arc welding operating.

1.Amperage degree

we know,the amperage degree is too high when we operate in welding process,we maybe burn throgh the equipment.this is operation mistake for welder,in order to solve the mistake,welder should reduce the amperage and increase the speed to balance the too much amperage.

2.power polarity

the welding types have AC and DC,the gas tungsten arc welding are created with power polarity.welding machine of AC can create a weld with the filler metal mixed.to protect the welding machine about it,it should use alternating current.A feature called AC balance control allows you to tailor the EP-to-EN ratio. if too much EP will etch the gas tungsten.

3.poor color

overheating can cause the poor color in steel weld,which not only affects the material's point,but degrades its resistance and mechanical properties.this is bad mistake for welder who operate welding.so that welder must control the mistake to prevent overheating, reduce amperage.we should how to do,of course ,Pulsing reduces heat input,it is a good method.

4.Weld Graininess

the weld grainess problem can be caused by filler metal problems.weld should adjust the filler brand in order fit for the applications.before welding,we should check the filler metal types in order to remove grease and moisture from the surface of welding.

my welding history

i apply for an entry-level welding job which it has a history for me.when a officer ask me "you ran much MIG?" I tell the forman that i can see the MIG welding tips.if fact ,i dont know what MIG is.and later ,she sents me to apply the welding.

but i can see the MIG welding tips clearly,so it thanks to foreman who is my teacher entering this profession。When welding out of position (vertical, horizontal, or overhead welding), keep the weld pool small for best weld bead control, and use the smallest wire diameter size you can. and be sure to match your contact tube, gun liner, and drive rolls to the wire size you are using.

the tips above is easy to me ,but it is important ,for the welding machine supply know ,i can see in my heart .if you have some problem about welding,if i can know ,i make sure to help you happly.

Welding can be a dangerous and unhealthy practice without the proper precautions; however, with the use of new technology and proper protection the risks of injury or death associated with welding can be greatly reduced. if you are welder ,you should know it.

i work in the welding ,happy and have a good mood.

arc welding problem

Maybe you know the method that it is jab method,and now ,you know it ,you want to quickly jab the rob into the work immediately.Just imagine the electrode is the match, and the location you wish to lay your welding bead is the striker.

for the arc welding is the popular in the world ,so it has so much porblem that we must see ,for example ,you should shield your eyes and body ,at the same time,you should know how to arc welding and welding value,when people can see welder ,you find the world is getting more and more beautiful.

Good welds are dependent on five techniques: correct amperage setting; correct arc length; correct rod selection and angle to the work; correct travel speed; and welding rods that have been stored and maintained properly.

and later ,you should know about welding machine technique ,the next technique that I prefer my collages to learn is a circular pattern. For someone who is learning how to weld, this technique is still relatively basic. It does take a little bit more practice and concentration than the zigzag pattern, but it is still a very achievable design. For this technique you will weld in slow, circular motions. Depending on the workpieces, and the weld you would like to make, you can either use small, precise circles, or a larger, more encompassing pattern. After a little practice with these arc welding techniques, you be know how to arc weld nearly any basic project that you wish to do.

翻墙上网,真的很是无奈

这几月,都没来有进行翻墙,现在的的GFW真的很是厉害的了,可现在的是有时还是需要来进行,其实我们没有作什么,只是想到看看而已,可就这个愿望也变的很是让人不可理解了,所以这儿的更新速度真的很是慢。
想好了的,好好的做好下一次的事情,结果向TOR发了一个邮件,才来的,可现在老费劲的了。但我相信是墙都会倒,只不过是时间问题的了。

这个国庆,疯狂了八天

这个是国庆是有计划的,到外面去玩了一圈,也在外面走了很多的地,看了不少的MM,不过有点小的了,自我感觉,可以是我太大的原因了吗?我其实也不大的吗。
最开心的是到海边的时候,到那个MM,后来被认作妹子,去了最深海,结果被一景区的管理员看见了,说那是深海,不让在前了,结果,我们都在那边浮了近一个小时,当然是有游泳圈的了,否则在那里面呆上一个小时就没体力的了。这次开心的最严重的后果是我的脸都让晒伤的了,可怜。但不知这个妹子怎么样,我想也可能会晒伤的吧,希望没有我的严重,毕竟是女孩子,不像我这个男孩子这样的,无所谓的。
回来的时候,在家好好的休息了二天,也抹了油,现在好点,但下次出去玩的时候,还是要注意点了。

Google首页新增天涯链接

今天一看google,首页有了新的变化,其如图是这样的:

这个加了一个问答,来吧,这两个也是与百度的百科与贴吧相似,从GG加强了从音乐方面的开始进攻百度有了初步的成效之后,又将其领域扩大到百科与贴吧,这也是从近战开始.
在07年的时候天涯获Google投资,当时遭到百度的全面封杀,这个也可以看到其百度与GG的较量到何种程度.
对于此, 人们一种猜测的是地天涯与GG的关系,一个是说是合作关系,一个说是一家,只是没有被公开,而我们从现有的来看也是只是合作关系,而对于是不是一家,这个还真没有什么证据,而今天看到GG的首页上也有天涯的链接,可见也关系非合作这样的简单.

绿坝你装了没有?

绿坝,你安了没,现在工信部在7.1后会在预装的PC上来安装其软件,那个时候,就会看到很多人想看到信息而不能看到,这个才是人们关心的问题,还有一个问题就是对其不信任,俗言,对其不信任才导致这样的一个局面了.
一个方面是我们不信任工信部,同时工信部也不信任我们可以管好自己,这样就形成现在的这样的一样个网上攻势,对其的反感让人感到无奈,虽说他们的初衷是好的,可结果是相反的个局面.
绿坝,据说一年可以这个公司赢利6个亿,可见其在工信部门的领导下,其效果可见一般,也是人们对此的一个最大的不满,这个局面,我想谷歌公司也是望尘莫及的.
可绿坝还是会继续,据说对一些词,如亲情,叔嫂,小姐,姐妹等词都给过滤了,可见其功能之强大到无缝之处,那一些带有有色的词就更不用说,难怪有人说,装了这个,就要六亲不认才可以.这个也只是人们据说是测试的,准确不准确现在还在清楚,可见我们以后可知道.
现在绿坝也是"绿霸",对此,在还没有装之前,就尽情的上网吧,以后的日子是什么样,就不知道了.

GG百宝箱

看了谷歌的百宝箱,从5.21号以来,一直在试用,其中最令人引目的是就是神奇罗盘了,这个也是最让人心奇的地方,也可以这个来看到相关的搜索,最不好的就是或最不准确就是时光隧道了,这个很多就是有点牵强,如当我搜索一个词,而看到是1953年内容竞争是现在写的是,可见这个不准确的程度,这个功能还有等改进,本来这个可以做为很好的一项历史查询,但很可惜的是,没有很准确的用途.

但也有很多的好的功用,如可看一天,或一年搜索的即时动态,也可以看到GG为搜索做出的最大的努力,以人为本的精神.

下一个倒下的BLOG会是谁

自从方兴东的博客出现问题之后,又有传blogbus出现了资金的短缺,而其副总裁兼首席运营官魏武挥将会辞职, 这也是一家很早的blog运营商,他们也曾尝试SNS服务,而目前博客大巴的定位是“跨界新媒体公司”,探索杂志、平面媒体业务,这个都有所行动,而他们宣称坚决不吃VC钱,而在此也开始用探索新的路径。
这次的COO辞职是不是也在说明一个问题呢,在我们看来,下一个倒下的会谁呢?

百度与GG较量到3G

说起百度与GG的恩怨可以说是说也说不完,从中国搜索领域开始两家都掐上了,一个是国际化人老大,一个是地方性的老大,两都优势明显,而中国这个市场上,GG由不服水土到逐渐反击,反应了GG的适应能力,也由于百度实在在中国的势力太大,于是开始向新的领域,而同时都看到了未来的元线搜索,这是一个全新的领域,也是一个高增长的领域,而GG先百度与中国移动合作,而百度也联合联通、电信两家,这样就会形成了两个阵容,一个是百度与GG,另一方面个则是移动与联通、电信;有意思的是,GG联合了中国另一个老大移动,GG看到了移动的用户数量,也看到了国家对TD的支持,百度只好与另外的进行联合了。
同时这也是移动运营商们开始对自己地盘的反击,如联通就想用百度影响来对抗移动,当然百度最想是移动,可由于慢别人一拍被别人抢足先登了,对此,百度与GG在新的领域的开始较量了,在这个百度不会再有优势,比起技术百度还是差了一点,这个方面,百度开始向中小学生进行侵入,而GG则是向大学生们侵入,不同的策略,如会不同的结果。
未来,都想把握,是谁能做的更好,更让用户安心,谁才会更得到其人心的力量。
